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.302C>T (p.T101I) alteration is located in exon 3 (coding exon 3) of the MTMR9 gene. This alteration results from a C to T substitution at nucleotide position 302, causing the threonine (T) at amino acid position 101 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
