The c.12259G>A (p.V4087M) alteration is located in exon 73 (coding exon 72) of the HECTD4 gene. This alteration results from a G to A substitution at nucleotide position 12259, causing the valine (V) at amino acid position 4087 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
