Genes affected

MTMR1 (HGNC:7449): (myotubularin related protein 1) This gene encodes a member of the myotubularin related family of proteins. Members of this family contain the consensus sequence for the active site of protein tyrosine phosphatases. Alternatively spliced variants have been described but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.628G>A (p.G210R) alteration is located in exon 6 (coding exon 6) of the MTMR1 gene. This alteration results from a G to A substitution at nucleotide position 628, causing the glycine (G) at amino acid position 210 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
