Ambry Genetics

Dec 21, 2023

The c.2959A>T (p.T987S) alteration is located in exon 23 (coding exon 22) of the MYOM3 gene. This alteration results from a A to T substitution at nucleotide position 2959, causing the threonine (T) at amino acid position 987 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
