The c.1094G>A (p.G365D) alteration is located in exon 10 (coding exon 10) of the CATIP gene. This alteration results from a G to A substitution at nucleotide position 1094, causing the glycine (G) at amino acid position 365 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
