Genes affected

MTM1 (HGNC:7448): (myotubularin 1) This gene encodes a dual-specificity phosphatase that acts on both phosphotyrosine and phosphoserine. It is required for muscle cell differentiation and mutations in this gene have been identified as being responsible for X-linked myotubular myopathy. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
• BP6: Variant X-150641301-T-C is Benign according to our data. Variant chrX-150641301-T-C is described in ClinVar as [Benign]. Clinvar id is 158983.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-150641301-T-C is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-0.008 with no splicing effect.
