Genes affected

MPC2 (HGNC:24515): (mitochondrial pyruvate carrier 2) Enables identical protein binding activity. Predicted to be involved in mitochondrial pyruvate transmembrane transport. Predicted to act upstream of or within mitochondrial acetyl-CoA biosynthetic process from pyruvate and positive regulation of insulin secretion involved in cellular response to glucose stimulus. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

MPC2 links:

DCAF6 (HGNC:30002): (DDB1 and CUL4 associated factor 6) The protein encoded by this gene is a ligand-dependent coactivator of nuclear receptors, including nuclear receptor subfamily 3 group C member 1 (NR3C1), glucocorticoid receptor (GR), and androgen receptor (AR). The encoded protein and DNA damage binding protein 2 (DDB2) may act as tumor promoters and tumor suppressors, respectively, by regulating the level of androgen receptor in prostate tissues. In addition, this protein can act with glucocorticoid receptor to promote human papillomavirus gene expression. [provided by RefSeq, Mar 2017]

Ambry Genetics

May 25, 2022

The c.31G>C (p.A11P) alteration is located in exon 2 (coding exon 1) of the MPC2 gene. This alteration results from a G to C substitution at nucleotide position 31, causing the alanine (A) at amino acid position 11 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
