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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with MTMR14-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.103_105del, results in the deletion of 1 amino acid(s) of the MTMR14 protein (p.Glu35del), but otherwise preserves the integrity of the reading frame. -
