The c.1171G>A (p.V391I) alteration is located in exon 11 (coding exon 11) of the CASC1 gene. This alteration results from a G to A substitution at nucleotide position 1171, causing the valine (V) at amino acid position 391 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
