Genes affected

MTMR14 (HGNC:26190): (myotubularin related protein 14) This gene encodes a myotubularin-related protein. The encoded protein is a phosphoinositide phosphatase that specifically dephosphorylates phosphatidylinositol 3,5-biphosphate and phosphatidylinositol 3-phosphate. Mutations in this gene are correlated with autosomal dominant centronuclear myopathy. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 18.[provided by RefSeq, Apr 2010]

The c.58G>T (p.G20C) alteration is located in exon 1 (coding exon 1) of the MTMR14 gene. This alteration results from a G to T substitution at nucleotide position 58, causing the glycine (G) at amino acid position 20 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
