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.797G>A (p.S266N) alteration is located in exon 12 (coding exon 9) of the MPP7 gene. This alteration results from a G to A substitution at nucleotide position 797, causing the serine (S) at amino acid position 266 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
