Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.3253G>A (p.G1085R) alteration is located in exon 26 (coding exon 25) of the MYOM3 gene. This alteration results from a G to A substitution at nucleotide position 3253, causing the glycine (G) at amino acid position 1085 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
