Nov 20, 2024

The c.297G>A (p.M99I) alteration is located in exon 3 (coding exon 3) of the CATIP gene. This alteration results from a G to A substitution at nucleotide position 297, causing the methionine (M) at amino acid position 99 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
