The c.83C>T (p.P28L) alteration is located in exon 1 (coding exon 1) of the CCDC34 gene. This alteration results from a C to T substitution at nucleotide position 83, causing the proline (P) at amino acid position 28 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
