Intellectual disability v5.532 | PLXNB2 |
Zornitza Stark gene: PLXNB2 was added gene: PLXNB2 was added to Intellectual disability - microarray and sequencing. Sources: Literature Mode of inheritance for gene: PLXNB2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PLXNB2 were set to 38458752 Phenotypes for gene: PLXNB2 were set to Syndromic disease MONDO:0002254, PLXNB2 -related Review for gene: PLXNB2 was set to GREEN Added comment: 8 individuals from 6 families with core features of amelogenesis imperfecta and sensorineural hearing loss. Intellectual disability, ocular disease, ear developmental abnormalities and lymphoedema were also present in multiple cases. WES and WGS identified biallelic pathogenic variants in PLXNB2 (missense, nonsense, splice and a multiexon deletion variants). Variants segregated with disease. PLXNB2 is a large transmembrane semaphorin receptor protein, and semaphorin-plexin signalling controls cellular interactions that are critical during development as well as in adult life stages. Plxnb2 expression was detected in differentiating ameloblasts in mice. Human phenotype overlaps with that seen in Plxnb2 knockout mice. Sources: Literature |
