Ambry Genetics

Aug 12, 2021

The c.1454G>A (p.R485H) alteration is located in exon 6 (coding exon 5) of the CCDC181 gene. This alteration results from a G to A substitution at nucleotide position 1454, causing the arginine (R) at amino acid position 485 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
