May 28, 2024

The c.716C>T (p.P239L) alteration is located in exon 6 (coding exon 5) of the RCN3 gene. This alteration results from a C to T substitution at nucleotide position 716, causing the proline (P) at amino acid position 239 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
