Ambry Genetics

Apr 26, 2024

The c.86T>A (p.F29Y) alteration is located in exon 1 (coding exon 1) of the CATSPER3 gene. This alteration results from a T to A substitution at nucleotide position 86, causing the phenylalanine (F) at amino acid position 29 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
