The c.3217T>G (p.Y1073D) alteration is located in exon 24 (coding exon 23) of the AGTPBP1 gene. This alteration results from a T to G substitution at nucleotide position 3217, causing the tyrosine (Y) at amino acid position 1073 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
