Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2024The c.2890G>A (p.E964K) alteration is located in exon 23 (coding exon 22) of the MYOM3 gene. This alteration results from a G to A substitution at nucleotide position 2890, causing the glutamic acid (E) at amino acid position 964 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
