Ambry Genetics

Jun 05, 2023

The c.155G>A (p.R52Q) alteration is located in exon 2 (coding exon 1) of the GSDMA gene. This alteration results from a G to A substitution at nucleotide position 155, causing the arginine (R) at amino acid position 52 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
