Collection Method:clinical testing

The c.322G>A (p.D108N) alteration is located in exon 5 (coding exon 4) of the ACTR3C gene. This alteration results from a G to A substitution at nucleotide position 322, causing the aspartic acid (D) at amino acid position 108 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
