Collection Method: clinical testing

The c.302A>G (p.Y101C) alteration is located in exon 5 (coding exon 4) of the CCDC129 gene. This alteration results from a A to G substitution at nucleotide position 302, causing the tyrosine (Y) at amino acid position 101 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
