There is sufficient evidence to promote this gene to Green at the next GMS panel update. EDEM3 is associated with a relevant phenotype in OMIM (MIM# 619493) and G2P with a 'strong' confidence level assertion. 12 individuals from 7 unrelated families identified by Polla et al. 2021 (PMID: 34143952) with various biallelic variants in the EDEM3 gene. Clinical characteristics were predominant for DD (12/12), ID (6/7), hypotonia (6/12) and facial dysmorphisms. (Arina Puzriakova (Genomics England Curator), 18 Jul 2022).
PMID: 34143952: 7 families (11 individuals) with 6x PTV and 2x missense variants with neurodevelopmental delay and variable facial dysmorphisms. The unaffected parents were all heterozygous carriers. Functional studies show loss of EDEM3 enzymatic activity. Sources: Literature (Zornitza Stark (Australian Genomics), 7 Aug 2021).
