1. Clinical and Genetic Profile of One Molecularly Confirmed and One Clinically Suspected Case of LZTR1 -Related Noonan Syndrome.
PMID:日期:2026-10-01Noonan syndrome (NS) is a clinically heterogeneous condition caused by pathogenic variants in genes of the RAS/MAPK signaling pathway, presenting as a spectrum of phenotypic features rather than a single uniform disorder. We report two unrelated female pediatric patients evaluated for LZTR1-related NS following whole-exome sequencing. The first patient presented with isolated short stature, subtle dysmorphic features, and normal neurodevelopment. The second displayed multisystem involvement including developmental delay, skeletal abnormalities, and auditory processing disorder. A heterozygous pathogenic variant in LZTR1 was confirmed in the first patient, while the second carried a heterozygous LZTR1 variant of uncertain significance, rendering her diagnosis provisional. Neither patient had congenital heart defects. These cases illustrate the marked phenotypic variability of LZTR1-related NS and underscore that, while cardiac defects may be absent in some individuals, appropriate cardiac surveillance remains necessary.

3. Delineation of a Novel Mirror Syndrome: NFIC Variants Cause Syndromic Intellectual Disability With Macrocephaly.
PMID:日期:2026-10-01Nuclear factor I (NFI) transcription factors regulate neural stem and progenitor differentiation during brain development. While NFIA, NFIB, and NFIX are linked to neurodevelopmental disorders, the role of NFIC (MIM: 600729) in human disease remains unclear. This study aimed to determine whether NFIC contributes to a neurodevelopmental syndrome, define its phenotype, and assess dosage-dependent effects. We established the first cohort of 11 individuals, including NFIC deletions and single nucleotide variants. Genotype-phenotype correlations, including critical region mapping, were performed. Murine data and bioinformatics were integrated to explore underlying pathomechanisms. We report 11 individuals with NFIC variants, including four with de novo SNVs and seven with deletions encompassing the gene, of whom nine have not been previously reported. A core phenotype of syndromic intellectual disability and macrocephaly was delineated. Opposing cranial phenotypes relative to proximal 19p13.3 duplication cases support a dosage-sensitive effect and a mirror-syndrome model. NFIC-related disorder represents a novel neurodevelopmental syndrome characterized by intellectual disability and macrocephaly, highlighting the importance of NFIC dosage supporting a mirror-syndrome model.

4. Expanding the Phenotypic and Functional Evidence for KCNK3 as a Neurodevelopmental Disorder Gene: A New Chinese Case and Drosophila Validation.
PMID:日期:2026-10-01Neurodevelopmental disorders (NDDs) are a group of developmental brain disorders caused by various genetic or acquired factors. OMIM has only recently associated the KCNK3 gene with developmental delay associated with sleep apnea (DDSA). Most prior studies on the KCNK3 gene have focused on PAH and cardiovascular diseases. In a 2-year-old girl presenting with generalized hypotonia and delayed language development, we identified a de novo missense variant in KCNK3 through the reanalysis of trio-whole exome sequencing (trio-WES) data. To further explore the relationship between KCNK3 and neurodevelopmental phenotypes, we conducted bidirectional expression regulation of the homologous gene Task7 based on the Drosophila model. Both overexpression and knockdown of the Task7 gene induced anxiety-like behaviors and impaired learning and memory. Notably, Task7 overexpression also led to reduced climbing ability and abnormal sleep patterns; collectively, these four phenotypes recapitulate the characteristic hallmarks of human neurodevelopmental disorders. This study represents the first application of a Drosophila model to demonstrate that KCNK3 functions as a dosage-sensitive regulator of neurodevelopment. While the underlying mechanisms remain to be fully elucidated, these findings position KCNK3 as a candidate gene for molecular screening and pave the way for future functional studies and therapeutic exploration in NDDs.

5. Novel Germline ELP1 Splice-Acceptor Variant in NF1-Negative Optic Pathway Glioma: Expanding the Clinical Spectrum Associated With ELP1 Variation.
PMID:日期:2026-10-01We report a 7-year-old boy with NF1-negative optic pathway glioma harboring a novel germline ELP1 splice-acceptor variant (NM_003640.5:c.2205-2A>G) identified by whole-exome sequencing. The variant was likely pathogenic (ACMG/AMP: PVS1, PM2) and inherited from an asymptomatic father, consistent with incomplete penetrance, expanding the limited evidence linking germline ELP1 variation to gliomas.

6. Clinical and Molecular Characterization of a RASopathy Cohort From Türkiye and an AMMECR1-Related Noonan Syndrome-Mimicking Phenotype.
PMID:日期:2026-10-01RASopathies comprise a group of congenital malformation syndromes with predominant neuro-cardio-facial-cutaneous involvement resulting from pathogenic variants in RAS/mitogen-activated protein kinase (MAPK) signaling pathway genes. In this study 33 patients are presented with their clinical and molecular findings as an RASopathy cohort including a family with an AMMECR1-related disorder. The diagnostic distribution of the cohort included Noonan syndrome (n = 18), neurofibromatosis type 1 (n = 8), and single cases of cardiofaciocutaneous syndrome, Costello syndrome, neurofibromatosis-Noonan syndrome, NF1 microdeletion syndrome, Noonan syndrome-like disorder with loose anagen hair, Noonan syndrome with multiple lentigines and AMMECR1-related midface hypoplasia, hearing impairment, elliptocytosis, and nephrocalcinosis (MIM# 300990). The most prevalent clinical manifestations were dermatological findings (90.9%), skeletal features (84.4%), cardiovascular involvement (75.8%), and typical craniofacial dysmorphism suggestive of RASopathy (72.7%). Variants were most frequently identified in PTPN11 and NF1, followed by single cases involving the BRAF, HRAS, LZTR1, RAF1, RIT1, SHOC2, and SOS1. Notably, one patient harbored a variant in AMMECR1, which is not involved in the RAS/MAPK pathway. Overall, this study delineates the clinical and molecular landscape of a cohort from Türkiye and underscores that the AMMECR1-related phenotype represents a distinct entity that closely mimics Noonan syndrome.

7. Claudin-11-Mediated Hypomyelinating Leukodystrophy 22: New Insights Into Pathogenic Mechanisms.
PMID:日期:2026-10-01CLDN11 has recently been associated with hypomyelinating leukodystrophy caused by de novo stop-loss variants. Here, we present a new case involving a homozygous variant in order to expand the genetic and clinical spectrum of the disease. We performed a comprehensive clinical, neuroradiological, and genetic evaluation in a child presenting with global developmental delay. Brain MRI and MR spectroscopy were obtained, and next-generation sequencing with parental segregation analysis was conducted. The patient presented with developmental delay, hypotonia, limb hypertonia, esotropia, and an absence of early developmental milestones in infancy, followed by partial motor improvement and persistent language and cognitive impairment. Brain MRI revealed diffuse supratentorial hypomyelination with stability over time. Genetic analysis identified a novel homozygous CLDN11 start-loss variant (c.1A>G; p.Met1Val), which is predicted to result in biallelic loss of function. Both parents were found to be heterozygous carriers. This case supports an autosomal recessive mechanism of CLDN11-related disease, which differs from the dominant stop-loss variants reported previously. The phenotype partially overlaps with that of earlier cases, but is characterized by milder motor involvement and more pronounced cognitive impairment. These findings broaden the mutational spectrum and suggest distinct pathogenic mechanisms, with important implications for diagnosis and genetic counselling.

8. Atypical Prenatal Phenotypic Spectrum: A Case Series of Four Unique Presentations With Genetic and Diagnostic Insights.
PMID:日期:2026-10-01Prenatal diagnosis of genetic syndromes often relies on structural anomalies; however, many monogenic disorders show atypical or evolving prenatal phenotypes, limiting imaging-based diagnosis. We report four fetuses with atypical presentations diagnosed by exome/genome sequencing. Pathogenic variants were identified in BBS1, SLC26A2, POMT2, and COL25A1. Prenatal findings included heterotaxy with complex heart disease, isolated long bone shortening, subtle CNS anomalies, and recurrent contractures. These cases highlight the variability in the prenatal phenotypic spectrum of genetic disorders and the value of genomic sequencing for accurate genetic counseling and reproductive decision-making.

9. Elucidating the Role of SET as a Key Contributor to Neurodevelopmental Disability Within the 9q34.11 Deletion Syndrome Interval.
PMID:日期:2026-10-01The 9q34.11 chromosomal region contains multiple neurodevelopmental genes involved in synaptic transmission, axonal structure and neuronal maturation. Pathogenic microdeletions, duplications and single nucleotide variants in numerous genes were previously linked with neurodevelopmental disorders (NDDs). Amongst them, SET has recently been implicated in a rare NDD with speech delay and facial dysmorphism. This study reports a female with a heterozygous de novo deletion impacting SET but not other NDD-associated genes at 9q34.11. The proband was initially diagnosed with atypical Rett syndrome with overlapping clinical features of SET haploinsufficiency. The deletion was confirmed using microarray and long-read sequencing. Subsequent quantitative proteomic evaluation identified a significant decrease of SET protein in patient-derived fibroblasts compared to control lines. This study provides insights into the proband's clinical course over their 28 year diagnostic odyssey, and emphasises the benefits of early speech therapy interventions. The proband had no functional speech, but regained the capacity to meaningfully communicate and articulate a limited vocabulary in adulthood, concordant with other reported non-paediatric cases of SET-NDD. This study expands current knowledge on the genotypic and phenotypic spectra of SET-NDD, and pinpoints a smaller 9q34.11 critical region excluding upstream NDD-associated genes, STXBP1 and SPTAN1, implicating SET as a significant NDD-associated gene.

10. Non-Coding c.*6C>T Variant in RBM8A Associated With Thrombocytopenia-Absent Radius (TAR) Syndrome in Three Indian Patients.
PMID:日期:2026-10-01Thrombocytopenia-absent radius (TAR) syndrome is a rare genetic disorder characterized by the absence of radius in the forearms and a decrease in platelet count. The molecular basis of TAR syndrome is linked to a heterozygous minimal deletion within the 1q21.1 region spanning 200 k bases (kb), resulting in a null allele and a nucleotide variation in RBM8A resulting in a hypomorphic allele. Previous studies have identified pathogenic variants in the coding regions of the RBM8A gene as the cause of TAR syndrome. However, the involvement of non-coding variants in disease pathogenesis remains largely unexplored. We investigated the association of a non-coding 3' UTR variant, c.*6C>T, in RBM8A with TAR syndrome in three individuals from two unrelated families of Indian origin. Our study provides evidence that this variant is associated with decreased stability of the transcript and is a hypomorphic allele with disease-causing impact when in trans with a null allele (1q21.1 deletion). The present work is the first application of an mRNA stability assay to directly detect RNA degradation in patients with non-coding RBM8A variants causing TAR syndrome.
