Description

The p.R203C variant (also known as c.607C>T), located in coding exon 1 of the FKRP gene, results from a C to T substitution at nucleotide position 607. The arginine at codon 203 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration has been reported in a muscular dystrophy cohort (Sframeli M et al. Neuromuscul Disord, 2017 Sep;27:793-803). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
