Ambry Genetics

Jan 24, 2024

The c.65G>A (p.R22Q) alteration is located in exon 1 (coding exon 1) of the MAZ gene. This alteration results from a G to A substitution at nucleotide position 65, causing the arginine (R) at amino acid position 22 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
