The c.241G>A (p.V81I) alteration is located in exon 3 (coding exon 3) of the ZG16B gene. This alteration results from a G to A substitution at nucleotide position 241, causing the valine (V) at amino acid position 81 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
