The c.1297T>A (p.S433T) alteration is located in exon 1 (coding exon 1) of the PDE12 gene. This alteration results from a T to A substitution at nucleotide position 1297, causing the serine (S) at amino acid position 433 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
