The c.928G>A (p.G310S) alteration is located in exon 9 (coding exon 9) of the CRTC1 gene. This alteration results from a G to A substitution at nucleotide position 928, causing the glycine (G) at amino acid position 310 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
