Description

The p.R633T variant (also known as c.1898G>C), located in coding exon 12 of the NEXN gene, results from a G to C substitution at nucleotide position 1898. The arginine at codon 633 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
