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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.675T>A (p.N225K) alteration is located in exon 7 (coding exon 7) of the MTMR1 gene. This alteration results from a T to A substitution at nucleotide position 675, causing the asparagine (N) at amino acid position 225 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
