Oct 20, 2024

The c.37T>G (p.L13V) alteration is located in exon 2 (coding exon 2) of the CCDC66 gene. This alteration results from a T to G substitution at nucleotide position 37, causing the leucine (L) at amino acid position 13 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
