The c.1846G>A (p.V616I) alteration is located in exon 18 (coding exon 18) of the SIDT1 gene. This alteration results from a G to A substitution at nucleotide position 1846, causing the valine (V) at amino acid position 616 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
