Dec 21, 2023

The c.751G>A (p.G251S) alteration is located in exon 4 (coding exon 4) of the CRAMP1 gene. This alteration results from a G to A substitution at nucleotide position 751, causing the glycine (G) at amino acid position 251 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
