The c.1291G>T (p.D431Y) alteration is located in exon 9 (coding exon 9) of the MXRA8 gene. This alteration results from a G to T substitution at nucleotide position 1291, causing the aspartic acid (D) at amino acid position 431 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
