The c.1108G>A (p.V370M) alteration is located in exon 1 (coding exon 1) of the ZNHIT2 gene. This alteration results from a G to A substitution at nucleotide position 1108, causing the valine (V) at amino acid position 370 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
