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

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.21505603).
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000267 (3/112221) while in subpopulation AMR AF= 0.00019 (2/10552). AF 95% confidence interval is 0.0000332. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
BS2
High Hemizygotes in GnomAd4 at 2 XL gene
