Ambry Genetics

Nov 18, 2022

The c.133A>G (p.T45A) alteration is located in exon 3 (coding exon 3) of the SPINK4 gene. This alteration results from a A to G substitution at nucleotide position 133, causing the threonine (T) at amino acid position 45 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
