The c.889A>G (p.I297V) alteration is located in exon 8 (coding exon 8) of the SIDT1 gene. This alteration results from a A to G substitution at nucleotide position 889, causing the isoleucine (I) at amino acid position 297 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
