Collection Method: clinical testing

The c.73G>A (p.G25R) alteration is located in exon 2 (coding exon 1) of the CRACR2B gene. This alteration results from a G to A substitution at nucleotide position 73, causing the glycine (G) at amino acid position 25 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
