Collection Method: clinical testing

The c.380C>G (p.S127C) alteration is located in exon 4 (coding exon 3) of the CRACR2B gene. This alteration results from a C to G substitution at nucleotide position 380, causing the serine (S) at amino acid position 127 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
