Collection Method: clinical testing

The c.679C>T (p.R227W) alteration is located in exon 4 (coding exon 4) of the ODF3L2 gene. This alteration results from a C to T substitution at nucleotide position 679, causing the arginine (R) at amino acid position 227 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
