Collection Method:clinical testing

The c.20G>A (p.G7D) alteration is located in exon 1 (coding exon 1) of the FAM185A gene. This alteration results from a G to A substitution at nucleotide position 20, causing the glycine (G) at amino acid position 7 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
