The c.301G>A (p.E101K) alteration is located in exon 3 (coding exon 2) of the RCN3 gene. This alteration results from a G to A substitution at nucleotide position 301, causing the glutamic acid (E) at amino acid position 101 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
