Genes affected

MVD (HGNC:7529): (mevalonate diphosphate decarboxylase) The enzyme mevalonate pyrophosphate decarboxylase catalyzes the conversion of mevalonate pyrophosphate into isopentenyl pyrophosphate in one of the early steps in cholesterol biosynthesis. It decarboxylates and dehydrates its substrate while hydrolyzing ATP. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.902C>T (p.A301V) alteration is located in exon 8 (coding exon 8) of the MVD gene. This alteration results from a C to T substitution at nucleotide position 902, causing the alanine (A) at amino acid position 301 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
