Ambry Genetics

Aug 14, 2024

The c.913A>G (p.R305G) alteration is located in exon 7 (coding exon 7) of the LRP2BP gene. This alteration results from a A to G substitution at nucleotide position 913, causing the arginine (R) at amino acid position 305 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
