Genes affected

GPNMB (HGNC:4462): (glycoprotein nmb) The protein encoded by this gene is a type I transmembrane glycoprotein which shows homology to the pMEL17 precursor, a melanocyte-specific protein. GPNMB shows expression in the lowly metastatic human melanoma cell lines and xenografts but does not show expression in the highly metastatic cell lines. GPNMB may be involved in growth delay and reduction of metastatic potential. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.469C>T (p.P157S) alteration is located in exon 4 (coding exon 4) of the GPNMB gene. This alteration results from a C to T substitution at nucleotide position 469, causing the proline (P) at amino acid position 157 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
