Ambry Genetics

Aug 12, 2022

The c.530G>A (p.R177Q) alteration is located in exon 1 (coding exon 1) of the GALNT15 gene. This alteration results from a G to A substitution at nucleotide position 530, causing the arginine (R) at amino acid position 177 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
