The c.589G>A (p.V197M) alteration is located in exon 2 (coding exon 2) of the HHIPL1 gene. This alteration results from a G to A substitution at nucleotide position 589, causing the valine (V) at amino acid position 197 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
