Ambry Genetics

Aug 16, 2021

The c.1054A>G (p.T352A) alteration is located in exon 1 (coding exon 1) of the ACTBL2 gene. This alteration results from a A to G substitution at nucleotide position 1054, causing the threonine (T) at amino acid position 352 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
