Genes affected

MTMR9 (HGNC:14596): (myotubularin related protein 9) This gene encodes a myotubularin-related protein that is atypical to most other members of the myotubularin-related protein family because it has no dual-specificity phosphatase domain. The encoded protein contains a double-helical motif similar to the SET interaction domain, which is thought to have a role in the control of cell proliferation. In mouse, a protein similar to the encoded protein binds with MTMR7, and together they dephosphorylate phosphatidylinositol 3-phosphate and inositol 1,3-bisphosphate. [provided by RefSeq, Jul 2008]

The c.440A>C (p.Y147S) alteration is located in exon 4 (coding exon 4) of the MTMR9 gene. This alteration results from a A to C substitution at nucleotide position 440, causing the tyrosine (Y) at amino acid position 147 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
