The c.3262C>T (p.P1088S) alteration is located in exon 26 (coding exon 26) of the FKBP15 gene. This alteration results from a C to T substitution at nucleotide position 3262, causing the proline (P) at amino acid position 1088 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
