Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.3082G>A (p.V1028I) alteration is located in exon 25 (coding exon 24) of the MYOM3 gene. This alteration results from a G to A substitution at nucleotide position 3082, causing the valine (V) at amino acid position 1028 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
