The c.832G>A (p.V278M) alteration is located in exon 9 (coding exon 7) of the HECW1 gene. This alteration results from a G to A substitution at nucleotide position 832, causing the valine (V) at amino acid position 278 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
