Ambry Genetics

Apr 07, 2023

The c.212G>A (p.R71Q) alteration is located in exon 3 (coding exon 3) of the SPINK4 gene. This alteration results from a G to A substitution at nucleotide position 212, causing the arginine (R) at amino acid position 71 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
