Collection Method: clinical testing

The c.238G>A (p.V80M) alteration is located in exon 3 (coding exon 2) of the FAM213A gene. This alteration results from a G to A substitution at nucleotide position 238, causing the valine (V) at amino acid position 80 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
