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.
Longitudinal Characterization of Males With X-Linked Creatine Transporter Deficiency: Final Results of a Multiyear Observational Study.
The purpose of the Vigilan observational study (ClinicalTrials.gov, NCT02931682) was to prospectively assess the natural history and developmental course of creatine transporter deficiency (CTD). Males with CTD aged 6 months to 65 years were evaluated at 6-month intervals for up to 4 years. Evaluations included neurodevelopmental assessments of intellectual functioning, adaptive functioning, challenging behaviors and the onset and progression of medical comorbidities. Fifty participants (median age, 7.6 years) were enrolled. The predominant CTD phenotype consisted of significant intellectual disabilities and limited skill development over time. Most participants had a history of febrile or nonfebrile seizures, gastrointestinal symptoms, and growth failure. All participants learned how to walk, 78% developed at least some verbal speech, and 34% communicated using phrases or sentences. Norm-referenced neurodevelopment assessments indicated declining standardized scores over time; however, absolute scores (i.e., age equivalent person ability scores) indicated that developmental gains were slower than average, particularly among older participants. Between-person differences in neurodevelopmental skills as a function of age did not match within-person change, suggesting a cohort effect. In this cohort, CTD was associated with significant and persistent intellectual disability. The use of absolute metrics from neurodevelopmental tests (e.g., person ability scores) allowed for the quantification of slow, but present, skill development.
Foundations of an Ovine Model of Fragile X Syndrome.
Fragile X Syndrome (FXS) is an X-linked neurodevelopmental disorder characterised by intellectual disability, developmental delays, anxiety, and social and behavioural challenges. Currently, no effective treatments exist to address the root cause of FXS. Mouse models are the most widely used for studying molecular pathogenesis and conducting preclinical treatment testing. However, therapeutic interventions that show promise in rodent models have yet to succeed in clinical trials. After evaluating the current models, we have developed an ovine model to address this clinical translation gap. We expect this model to more accurately reflect the human condition in brain size, structure, and neurodevelopmental trajectory. We aim to establish this model as a valuable preclinical platform for testing therapies for FXS. To generate the sheep model, we used CRISPR-Cas9 dual-guide editing to knock out the Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene in ovine embryos. Two founder animals were created, one ram (male) and one ewe (female), both of which carried FMR1 gene knockouts. The ewe carries inactivating mutations on both alleles, with the edits in both animals resulting in no detectable Fragile X Messenger Ribonucleoprotein (FMRP) as expected. Both founders have undergone molecular characterisation and basic health checks, with the female founder showing increased joint flexibility, a characteristic of FXS. The ram has been used for breeding, with the successful transmission of the edited allele to his offspring. Importantly, specific lamb cohorts for postnatal treatment testing can be produced efficiently utilising accelerated breeding methods and preimplantation selection.
Altered Brain Structure in an ATRX-Deficient Mouse Model of Autism Spectrum Disorder.
Mutations in the ATRX gene are a primary cause of alpha-thalassemia intellectual disability X-linked (ATRX) syndrome, which is characterized by intellectual disability, autism, and a range of brain structural abnormalities, including microcephaly. We previously showed that mice with conditional ATRX ablation in forebrain excitatory neurons display deficits in fear memory and autism-related behaviors, with some effects exhibiting sexual dimorphism. In this study, we used high-resolution magnetic resonance imaging (MRI) to systematically characterize brain structural changes associated with these behavioral abnormalities. Whole-brain analysis revealed male-specific microcephaly, while subregional analysis identified significant reductions in hippocampal structures and increased volume of the caudal cortex in mutant animals of both sexes. We also identified structural alterations in regions retaining ATRX expression, such as the thalamus, midbrain, cerebellum, and several fiber tracts. These findings suggest that ATRX loss disrupts the coordinated development of interconnected brain regions. Overall, our results implicate impaired cortico-thalamic-cerebellar connectivity as a potential neural substrate underlying the autistic-like behaviors observed in this mouse model, providing new insights into the neurobiological basis of ATR-X syndrome. Changes in a gene called ATRX are known to affect brain development and are linked to intellectual disability and autism. In our previous work, we found that removing this gene early in brain development caused mice to show behaviors like those seen in people with autism. In this study, we used detailed brain scans to see if these behavioral changes were linked to differences in brain structure. We found that male mice without ATRX had smaller brains and bodies, while female mice did not show the same brain size reduction. However, both male and female mice had smaller areas of the brain important for memory and movement, and larger areas involved in thinking and sensing. We also saw changes in parts of the brain where ATRX was still present, suggesting that early changes in one area can affect how the whole brain develops. These findings help us understand how early disruptions in brain development might lead to autism‐related behaviors.
