Emerging role of KDM5C in X-linked intellectual disability based on human genetic data and zebrafish models.
Claes-Jensen syndrome is a rare X-linked syndromic neurodevelopmental disorder by pathogenic variants in lysine specific demethylase 5C (KDM5C), a lysine-specific histone demethylase. In this study, clinical evaluations were conducted in affected individuals and carrier females. X-chromosome inactivation (XCI) assays were performed to assess genotype-phenotype correlations. Functional studies evaluated variant effects on RNA transcription, protein expression, and stability. Zebrafish models were used for in vivo validation. RNA sequencing with KEGG and GO analyses identified dysregulated genes and pathways, further confirmed in zebrafish. Two novel KDM5C variants NM_004187.5:c.3019del and NM_004187.5:c.782-2A>T were identified in unrelated families with X-linked ID. Affected males presented with short stature, microcephaly, language delay, and intellectual disability, while carrier females showed milder features including learning difficulties and short stature. Skewed XCI in some carriers suggested a role in phenotypic variability. Both variants impair RNA transcription, protein expression and stability. Zebrafish models recapitulated neurodevelopmental and behavioral abnormalities. Transcriptomic analyses revealed disrupted antiviral and interferon-related signaling, implicating aberrant immune activation. Pharmacologic inhibition of the Toll-like receptor pathway ameliorated mutant phenotypes, highlighting neuroinflammation as a potential therapeutic target for KDM5C-related disorders. These findings expand the mutational spectrum of KDM5C-associated ID and uncover a novel pathogenic mechanism between KDM5C dysfunction, protein instability, and dysregulated inflammatory signaling.
Orofacial clefting in PHF6-related Börjeson-Forssman-Lehmann syndrome.
Börjeson-Forssman-Lehmann syndrome (BFLS) is a rare X-linked neurodevelopmental disorder caused by pathogenic variants in the plant homeodomain finger protein 6 (PHF6) gene. Core features include developmental delay, intellectual disability, dysmorphic craniofacial characteristics, obesity, hypogonadism and digital anomalies. Orofacial clefting has not been recognised as part of the canonical phenotype and is rarely reported in association with BFLS. One cohort study listed cleft lip and/or palate as an uncommon feature without individual case details, and a separate report described a female with a nonsense PHF6 variant and clefting of the hard and soft palate. Here, we describe a BFLS female with a de novo missense PHF6 variant who presented with cleft palate. This case adds to the emerging evidence that clefting, though uncommon, may be a recurrent manifestation. It supports the inclusion of PHF6 in the genetic testing of patients presenting with syndromic orofacial clefting when accompanied by neurodevelopmental delay or dysmorphism.
Case Report: A female case of X-linked intellectual disability syndrome type 34 caused by a NONO frameshift variant and literature review.
To characterize the clinical and genetic features of a female infant with X-linked intellectual disability syndrome type 34 (MRXS34) caused by a de novo NONO frameshift variant, expanding the understanding of phenotypic mechanisms in females for this X-linked disorder. Retrospective study of the clinical data of a 10-month-old female infant diagnosed with MRXS34 due to NONO gene variation in June 2024, along with a literature review. The proband presented with global developmental delay, relative macrocephaly, generalized hypotonia, cardiac anomalies (patent foramen ovale, moderate tricuspid regurgitation, pulmonary hypertension), etc. Whole-exome sequencing (WES) identified a de novo heterozygous frameshift variant in NONO (NM_007363.5): c.994del (p.Gln322Lysfs*31), confirmed absent in both parents by Sanger sequencing. X-chromosome inactivation (XCI) analysis revealed extreme skewing (99% inactivation of the paternal X-chromosome). Transcriptome sequencing demonstrated significantly reduced NONO expression (TPM = 20.70 vs. controls 52.34 ± 5.81). Literature review encompassing 27 postnatal MRXS34 cases (all male) consistently reported intellectual disability/developmental delay (100%), craniofacial dysmorphism (100%), cardiac defects (91.3%, predominantly left ventricular non-compaction), and corpus callosum abnormalities (85%). We report the first molecularly confirmed female MRXS34 patient. Her full phenotypic manifestation is attributed to the de novo NONO loss-of-function variant combined with extreme non-random XCI. This case critically expands the clinical spectrum of MRXS34, underscores the diagnostic importance of XCI analysis in females with XLID phenotypes, and provides insights into the mechanisms enabling female expression of X-linked recessive disorders.
A Novel MID1 Mutation Identified in a Patient With Craniofacial Anomalies and X-Linked Intellectual Disability.
Genetic variations in MID1 were initially identified as the cause of X-linked Opitz G/BBB syndrome, which is characterized by hypertelorism, hypospadias, and a high incidence of intellectual disability. However, increasing evidence has shown that MID1 mutations are associated with a broader spectrum of phenotypes, and the genotype-phenotype correlation remains unclear. In this study, the authors report a 4-year-old boy presenting with congenital unilateral nostril hypoplasia, preaxial polydactyly, hemispheric brain asymmetry, and moderate intellectual disability. Whole-exome sequencing identified a novel hemizygous missense variant in MID1 (c.1600G>T; p.Val534Leu), inherited from an unaffected heterozygous mother and also present in the proband's clinically normal sister. Functional analysis suggested that this variant may affect protein-protein interactions and microtubule-associated cellular processes. In addition, expression profiling revealed that MID1 is highly enriched in the central nervous system, supporting its essential role in neurodevelopment. Structural modeling with AlphaFold3 showed preservation of the overall protein fold, whereas DynaMut2 predicted local destabilization and increased hydrophobic packing near the variant site. The variant segregated in the family in an X-linked manner and was classified as possibly damaging by PolyPhen-2. In conclusion, our findings expand the mutational and phenotypic spectrum of MID1-related disorders and suggest a potential pathogenic role of this variant in neurodevelopmental and craniofacial abnormalities.
A novel KDM6A c.2429dup mutation causing kabuki syndrome type 2 identified in a fetus with increased nuchal translucency.
Kabuki syndrome (KS) is a rare, multiple congenital anomaly syndrome, characterized by dysmorphic facial features, skeletal anomalies, dermatoglyphic abnormalities, developmental delay, mild-to-moderate intellectual disability, and postnatal growth restriction. KS type 1 (KS1, OMIM 147920) is caused by autosomal dominant pathogenic mutations in KMT2D, and KS type 2 (KS2, OMIM 300867) is caused by X-linked dominant pathogenic mutations in KDM6A. To identify the genetic etiologies in a fetus with increased nuchal translucency (NT) observed by ultrasound at 11+6 weeks of gestation. Chromosomal microarray analysis (CMA) and trio-exome sequencing (trio-ES) were performed on amniotic fluid sample to investigate the potential genetic causes. Sanger sequencing was utilized for validation of the candidate variant. A 28-year-old Chinese pregnant woman was referred for prenatal evaluation due to fetal increased NT (NT = 6.7 mm). CMA yielded a normal result, with no pathogenic or likely pathogenic copy number variants, or mosaicism detected. However, trio-ES identified a novel de novo frameshift mutation (NM_021140.4: c.2429dup (p.Thr811Aspfs*2)) in the KDM6A gene. This variant was classified as pathogenic (PVS1 + PS2_Supporting + PM2_Supporting) based on the American College of Medical Genetics and Genomics guidelines. The fetus was diagnosed with X-linked dominant KS2. The identification of this novel frameshift variant, together with the first report of increased NT as a prenatal feature, enriched both the mutation spectrum and prenatal phenotypic spectrum of KS2. These findings underscore the diagnostic utility of ES for fetuses with increased NT, especially when CMA yields normal results.
