The c.526G>A (p.V176I) alteration is located in exon 5 (coding exon 4) of the HDHD2 gene. This alteration results from a G to A substitution at nucleotide position 526, causing the valine (V) at amino acid position 176 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
