Collection Method: clinical testing

The c.500T>A (p.V167E) alteration is located in exon 2 (coding exon 2) of the FAM198A gene. This alteration results from a T to A substitution at nucleotide position 500, causing the valine (V) at amino acid position 167 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
