GeneDx RCV000185967 SCV000238925 pathogenic not provided 2014-05-27 criteria provided, single submitter clinical testing c.1892delT: p.Leu631Stop (L631X) in exon 11 of the HLCS gene (NM_000411.6). The normal sequence with the base that is deleted in braces is: GCCCT{T}AAGA. The c.1892delT mutation in the HLCS gene causes the normal Leucine codon at amino acid position 631 to be changed to a Stop codon, denoted p.Leu631Stop. This mutation is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Mutations in the HLCS gene are associated with the autosomal recessive disorder holocarboxylase synthetase deficiency. Although this mutation has not been previously reported to our knowledge, it is expected to be a pathogenic mutation. The variant is found in MITONUC-MITOP panel(s).
