Collection Method: clinical testing

The c.86G>C (p.R29P) alteration is located in exon 2 (coding exon 1) of the REPIN1 gene. This alteration results from a G to C substitution at nucleotide position 86, causing the arginine (R) at amino acid position 29 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
