Collection Method: clinical testing

The c.496G>C (p.E166Q) alteration is located in exon 2 (coding exon 2) of the ACTRT3 gene. This alteration results from a G to C substitution at nucleotide position 496, causing the glutamic acid (E) at amino acid position 166 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
