Collection Method: clinical testing

The c.416C>T (p.P139L) alteration is located in exon 4 (coding exon 4) of the ODF3L1 gene. This alteration results from a C to T substitution at nucleotide position 416, causing the proline (P) at amino acid position 139 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
