The c.517A>G (p.I173V) alteration is located in exon 1 (coding exon 1) of the FAHD1 gene. This alteration results from a A to G substitution at nucleotide position 517, causing the isoleucine (I) at amino acid position 173 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
