Ambry Genetics

Feb 13, 2023

The c.419A>G (p.K140R) alteration is located in exon 3 (coding exon 2) of the BRINP2 gene. This alteration results from a A to G substitution at nucleotide position 419, causing the lysine (K) at amino acid position 140 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
