Ambry Genetics

Dec 19, 2023

The c.1109C>T (p.S370L) alteration is located in exon 7 (coding exon 7) of the ACSM1 gene. This alteration results from a C to T substitution at nucleotide position 1109, causing the serine (S) at amino acid position 370 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
