Ambry Genetics

Nov 21, 2023

The c.76C>T (p.R26C) alteration is located in exon 2 (coding exon 2) of the LIN52 gene. This alteration results from a C to T substitution at nucleotide position 76, causing the arginine (R) at amino acid position 26 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
