Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.3108G>C (p.E1036D) alteration is located in exon 25 (coding exon 24) of the MYOM3 gene. This alteration results from a G to C substitution at nucleotide position 3108, causing the glutamic acid (E) at amino acid position 1036 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
