not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.4307G>A (p.S1436N) alteration is located in exon 37 (coding exon 36) of the MYOM3 gene. This alteration results from a G to A substitution at nucleotide position 4307, causing the serine (S) at amino acid position 1436 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
