Collection Method:clinical testing

The c.214A>G (p.T72A) alteration is located in exon 4 (coding exon 3) of the ACTR3C gene. This alteration results from a A to G substitution at nucleotide position 214, causing the threonine (T) at amino acid position 72 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
