Feb 10, 2022

The c.647G>C (p.R216T) alteration is located in exon 8 (coding exon 8) of the ERO1A gene. This alteration results from a G to C substitution at nucleotide position 647, causing the arginine (R) at amino acid position 216 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
