The c.865G>A (p.A289T) alteration is located in exon 11 (coding exon 11) of the PDXDC1 gene. This alteration results from a G to A substitution at nucleotide position 865, causing the alanine (A) at amino acid position 289 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
