Jul 14, 2021

The c.58G>A (p.A20T) alteration is located in exon 1 (coding exon 1) of the CCDC34 gene. This alteration results from a G to A substitution at nucleotide position 58, causing the alanine (A) at amino acid position 20 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
