Genes affected

MMEL1 (HGNC:14668): (membrane metalloendopeptidase like 1) The protein encoded by this gene is a member of the neutral endopeptidase (NEP) or membrane metallo-endopeptidase (MME) family. Family members play important roles in pain perception, arterial pressure regulation, phosphate metabolism and homeostasis. This protein is a type II transmembrane protein and is thought to be expressed as a secreted protein. This gene is expressed mainly in testis with weak expression in the brain, kidney, and heart.

The c.2044G>C (p.G682R) alteration is located in exon 21 (coding exon 20) of the MMEL1 gene. This alteration results from a G to C substitution at nucleotide position 2044, causing the glycine (G) at amino acid position 682 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
