Labcorp Genetics (formerly Invitae), Labcorp RCV001963147 SCV002242174 pathogenic Deficiency of hydroxymethylglutaryl-CoA lyase 2020-12-23 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with HMGCL-related conditions. This variant is a gross deletion of the genomic region encompassing exon(s) 8-9 of the HMGCL gene. The 5' boundary is likely confined to intron 7. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to lead to nonsense mediated decay, it is expected to alter mRNA translation or result in a truncated protein product. For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the HMGCL protein. Other variant(s) that disrupt this region (p.Glu286*) have been determined to be pathogenic (Invitae). This suggests that variants that disrupt this region of the protein are likely to be causative of disease.
