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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.2444A>G (p.Q815R) alteration is located in exon 19 (coding exon 18) of the SARDH gene. This alteration results from a A to G substitution at nucleotide position 2444, causing the glutamine (Q) at amino acid position 815 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
