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]

MVD Gene-Disease associations (from GenCC):

• porokeratosis 7, multiple types

  Inheritance: AD Classification: STRONG Submitted by: Genomics England PanelApp, Labcorp Genetics (formerly Invitae), G2P
• disseminated superficial actinic porokeratosis

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BP6: Variant 16-88653318-T-C is Benign according to our data. Variant chr16-88653318-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 790328.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
