Collection Method: clinical testing

The c.349C>T (p.H117Y) alteration is located in exon 3 (coding exon 3) of the CCDC113 gene. This alteration results from a C to T substitution at nucleotide position 349, causing the histidine (H) at amino acid position 117 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
