The c.3293G>A (p.G1098D) alteration is located in exon 25 (coding exon 23) of the TECPR1 gene. This alteration results from a G to A substitution at nucleotide position 3293, causing the glycine (G) at amino acid position 1098 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
