The c.1225C>T (p.P409S) alteration is located in exon 11 (coding exon 11) of the CRTC1 gene. This alteration results from a C to T substitution at nucleotide position 1225, causing the proline (P) at amino acid position 409 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
