Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.230T>C (p.M77T) alteration is located in exon 4 (coding exon 4) of the MYL7 gene. This alteration results from a T to C substitution at nucleotide position 230, causing the methionine (M) at amino acid position 77 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
