Arina Puzriakova Added comment: Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). There is sufficient evidence to promote this gene to Green at the next GMS panel update (see details below). ----- Hengel et al. 2021 (PMID: 34022130) report 8 unrelated families, all with different biallelic variants in the BCAS3 gene. All affected individuals (15 total, +1 additional proband but with unphased variants but consistent phenotype) had severe GDD and ID, with 10 subjects having minimal vocabulary and 4 never learning to speak. All probands had a severe motor disorder with pyramidal tract involvement resulting in hyperreflexia and spasticity of the lower limbs (15/15). Other variable features observed in the cohort include microcephaly, short stature, seizures, and dysmorphic facial features. |

Zornitza Stark gene: BCAS3 was added gene: BCAS3 was added to Intellectual disability. Sources: Literature Mode of inheritance for gene: BCAS3 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: BCAS3 were set to 34022130 Phenotypes for gene: BCAS3 were set to Syndromic neurodevelopmental disorder Review for gene: BCAS3 was set to GREEN Added comment: 15 individuals from eight unrelated families with germline bi-allelic loss-of-function variants in BCAS3. All probands share a global developmental delay accompanied by pyramidal tract involvement, microcephaly, short stature, strabismus, dysmorphic facial features, and seizures. Patient fibroblasts confirmed absence of BCAS3 protein. Sources: Literature |
