Invitae | RCV000793164 | SCV000932505 | pathogenic | Pyruvate dehydrogenase E1-alpha deficiency | 2018-07-11 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. A different truncation (p.Glu358Glyfs*12) that lies downstream of this variant has been determined to be pathogenic (PMID: 1907799). This suggests that deletion of this region of the PDHA1 protein is causative of disease. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acids is currently unknown. This variant has not been reported in the literature in individuals with PDHA1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the PDHA1 gene (p.Ser331Argfs*15). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 60 amino acids of the PDHA1 protein. |
