Description

This variant, c.423_425del, results in the deletion of 1 amino acid(s) of the ACADM protein (p.Lys144del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (no rsID available, gnomAD 0.03%). This variant has been observed in individual(s) with clinical features of medium chain acyl-CoA dehydrogenase (MCAD) deficiency (PMID: 20434380, 21083904, 23028790; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 281055). For these reasons, this variant has been classified as Pathogenic.
