Description

The p.R85S variant (also known as c.253C>A), located in coding exon 2 of the NTRK1 gene, results from a C to A substitution at nucleotide position 253. The arginine at codon 85 is replaced by serine, an amino acid with dissimilar properties. This variant was detected in the homozygous state in an individual with congenital insensitivity to pain with anhidrosis (CIPA) who also had another homozygous variant in NTRK1 (c.429-1G>C) (Mardy S et al. Am J Hum Genet, 1999 Jun;64:1570-9). In addition, the p.R85S variant was found to segregate with CIPA in two affected siblings with CIPA, who were both compound heterozygotes for NTRK1 p.R85S (c.253C>A) and p.R692C (c.2074C>T) (Hartono F et al. Int J Surg Case Rep, 2020 Jul;73:213-217). Protein functional studies suggest that this alteration does not impair normal processing or autophosphorylation of NTRK1 (Mardy S et al. Hum Mol Genet, 2001 Feb;10:179-88; Miranda C et al. J Biol Chem, 2002 Feb;277:6455-62). This amino acid position is poorly conserved in available vertebrate species. 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.
