Ambry Genetics

Mar 18, 2024

The c.725G>T (p.R242L) alteration is located in exon 2 (coding exon 2) of the MBLAC2 gene. This alteration results from a G to T substitution at nucleotide position 725, causing the arginine (R) at amino acid position 242 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
