Ambry Genetics

Aug 12, 2021

The c.61C>T (p.R21C) alteration is located in exon 3 (coding exon 2) of the MAB21L3 gene. This alteration results from a C to T substitution at nucleotide position 61, causing the arginine (R) at amino acid position 21 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
