Ambry Genetics

Apr 04, 2023

The c.566G>A (p.R189H) alteration is located in exon 5 (coding exon 5) of the CATSPER4 gene. This alteration results from a G to A substitution at nucleotide position 566, causing the arginine (R) at amino acid position 189 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
