The c.1117G>A (p.V373M) alteration is located in exon 7 (coding exon 7) of the CUZD1 gene. This alteration results from a G to A substitution at nucleotide position 1117, causing the valine (V) at amino acid position 373 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
