Genes affected

SARDH (HGNC:10536): (sarcosine dehydrogenase) This gene encodes an enzyme localized to the mitochondrial matrix which catalyzes the oxidative demethylation of sarcosine. This enzyme is distinct from another mitochondrial matrix enzyme, dimethylglycine dehydrogenase, which catalyzes a reaction resulting in the formation of sarcosine. Mutations in this gene are associated with sarcosinemia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Oct 2008]

The c.2683G>T (p.V895L) alteration is located in exon 21 (coding exon 20) of the SARDH gene. This alteration results from a G to T substitution at nucleotide position 2683, causing the valine (V) at amino acid position 895 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
