Genes affected

MMD2 (HGNC:30133): (monocyte to macrophage differentiation associated 2) This gene encodes a member of the PAQR (progestin and adipoQ receptor) family. Members of this family are evolutionarily conserved with significant sequence identity to bacterial hemolysin-like proteins and are defined by a set of seven transmembrane domains. The protein encoded by this gene localizes to the Golgi apparatus to modulate Ras signaling. Alternative splicing results in multiple transcript variants and protein isoforms.

The c.486G>T (p.Q162H) alteration is located in exon 6 (coding exon 6) of the MMD2 gene. This alteration results from a G to T substitution at nucleotide position 486, causing the glutamine (Q) at amino acid position 162 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
