The c.748G>A (p.G250R) alteration is located in exon 10 (coding exon 10) of the ATXN7L3 gene. This alteration results from a G to A substitution at nucleotide position 748, causing the glycine (G) at amino acid position 250 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
