Ambry Genetics

Nov 10, 2022

The c.3263G>A (p.R1088H) alteration is located in exon 24 (coding exon 24) of the GLG1 gene. This alteration results from a G to A substitution at nucleotide position 3263, causing the arginine (R) at amino acid position 1088 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
