Apr 25, 2022

The c.247A>G (p.T83A) alteration is located in exon 1 (coding exon 1) of the CCDC105 gene. This alteration results from a A to G substitution at nucleotide position 247, causing the threonine (T) at amino acid position 83 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
