The c.569T>A (p.V190D) alteration is located in exon 2 (coding exon 1) of the HDHD3 gene. This alteration results from a T to A substitution at nucleotide position 569, causing the valine (V) at amino acid position 190 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
