Genes affected

PMVK (HGNC:9141): (phosphomevalonate kinase) This gene encodes a peroxisomal enzyme that is a member of the galactokinase, homoserine kinase, mevalonate kinase, and phosphomevalonate kinase (GHMP) family of ATP-dependent enzymes. The encoded protein catalyzes the conversion of mevalonate 5-phosphate to mevalonate 5-diphosphate, which is the fifth step in the mevalonate pathway of isoprenoid biosynthesis. Mutations in this gene are linked to certain types of porokeratosis including disseminated superficial porokeratosis. Alternative splicing results in multiple transcript variants.

The c.223G>C (p.D75H) alteration is located in exon 3 (coding exon 3) of the PMVK gene. This alteration results from a G to C substitution at nucleotide position 223, causing the aspartic acid (D) at amino acid position 75 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
