Collection Method: clinical testing

The c.1037G>A (p.R346H) alteration is located in exon 13 (coding exon 12) of the ERGIC2 gene. This alteration results from a G to A substitution at nucleotide position 1037, causing the arginine (R) at amino acid position 346 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
