The c.86C>T (p.P29L) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a C to T substitution at nucleotide position 86, causing the proline (P) at amino acid position 29 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
