Intellectual disability v5.532 ZFX Achchuthan Shanmugasundram Added comment: Comment on phenotypes: This gene has now been associated with phenotype in OMIM (MIM #301118), but not yet in Gene2Phenotype.
Intellectual disability v5.532 ZFX Achchuthan Shanmugasundram Phenotypes for gene: ZFX were changed from X-linked neurodevelopmental disorder with recurrent facial gestalt to Intellectual developmental disorder, X-linked syndromic 37, OMIM:301118
Intellectual disability v5.506 ZFX Tracy Lester reviewed gene: ZFX: Rating: GREEN; Mode of pathogenicity: None; Publications: 38325380; Phenotypes: Intellectual disability, developmental delay, behavioural abnormalities, hypotonia, dysmorphic facies; Mode of inheritance: X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Intellectual disability v5.487 ZFX Sarah Leigh changed review comment from: A single ZFX variant has been associated with a neurodevelopmental disorder, that has a Rett syndrome-like phenotype disorder, in a 14 year old male. The ZFX variant was allelic with another X-linked variant in SHROOM4. These variants were inherited from the mother, who had random X inactivation pattern (PMID: 26740508).
PMID: 38325380 reports 11 ZFX variants in 18 subjects from 16 unrelated families (14 males and 4 females) with an X-linked neurodevelopmental disorder with recurrent facial gestalt. Seven variants were truncating and the remaining were missense variants within the Zinc finger array. In the pedigree of family 6 (figure 3, PMID: 38325380), it was apparent that there were female carriers of the ZFX variant (GRCh38 chrX: 24229396A>G, c.2438A>G, p.Tyr774Cys) with hyperparathyroidism and two affected males and one affected female, with the neurodevelopmental disorder. It appeared that skewed X-inactivation in the female carriers was responsible for the different phenotypic features. The association between ZFX variants and a novel neurodevelopmental disorder, was further supported by functional studies showing altered transcriptional activity in missense variants and altered behavior in a zebrafish loss-of-function model.; to: To date, germline variants in ZFX have not been associated with a phenotype in OMIM or Gen2Phen.
