Ambry Genetics

Jun 24, 2022

The c.1162G>T (p.A388S) alteration is located in exon 10 (coding exon 10) of the ACTR8 gene. This alteration results from a G to T substitution at nucleotide position 1162, causing the alanine (A) at amino acid position 388 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
