Genes affected
MPP2 (HGNC:7220): (MAGUK p55 scaffold protein 2) Palmitoylated membrane protein 2 is a member of a family of membrane-associated proteins termed MAGUKs (membrane-associated guanylate kinase homologs). MAGUKs interact with the cytoskeleton and regulate cell proliferation, signaling pathways, and intracellular junctions. Palmitoylated membrane protein 2 contains a conserved sequence, called the SH3 (src homology 3) motif, found in several other proteins that associate with the cytoskeleton and are suspected to play important roles in signal transduction.

The c.1562T>A (p.V521D) alteration is located in exon 13 (coding exon 12) of the MPP2 gene. This alteration results from a T to A substitution at nucleotide position 1562, causing the valine (V) at amino acid position 521 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
