Genes affected

MPP7 (HGNC:26542): (MAGUK p55 scaffold protein 7) The protein encoded by this gene is a member of the p55 Stardust family of membrane-associated guanylate kinase (MAGUK) proteins, which function in the establishment of epithelial cell polarity. This family member forms a complex with the polarity protein DLG1 (discs, large homolog 1) and facilitates epithelial cell polarity and tight junction formation. Polymorphisms in this gene are associated with variations in site-specific bone mineral density (BMD). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.1462C>T (p.P488S) alteration is located in exon 18 (coding exon 15) of the MPP7 gene. This alteration results from a C to T substitution at nucleotide position 1462, causing the proline (P) at amino acid position 488 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
