Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.58G>A (p.E20K) 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 58, causing the glutamic acid (E) at amino acid position 20 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
