Genes affected

FKBP14 (HGNC:18625): (FKBP prolyl isomerase 14) The protein encoded by this gene is a member of the FK506-binding protein family of peptidyl-prolyl cis-trans isomerases. The encoded protein is found in the lumen of the endoplasmic reticulum, where it is thought to accelerate protein folding. Defects in this gene are a cause of a type of Ehlers-Danlos syndrome (EDS). Both a protein-coding variant and noncoding variants are transcribed from this gene. [provided by RefSeq, Mar 2012]

The p.I199L variant (also known as c.595A>T), located in coding exon 4 of the FKBP14 gene, results from an A to T substitution at nucleotide position 595. The isoleucine at codon 199 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
