Ambry Genetics

Feb 16, 2023

The c.422G>A (p.R141H) alteration is located in exon 4 (coding exon 4) of the MSRB2 gene. This alteration results from a G to A substitution at nucleotide position 422, causing the arginine (R) at amino acid position 141 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
