Mutation analysis of the PLOD1 gene: an efficient multistep approach to the molecular diagnosis of the kyphoscoliotic type of Ehlers-Danlos syndrome (EDS VIA)

Mol Genet Metab. Sep-Oct 2005;86(1-2):269-76. doi: 10.1016/j.ymgme.2005.04.014. Epub 2005 Jun 24.

Abstract

The kyphoscoliotic type of Ehlers-Danlos syndrome (EDS VIA) is an inheritable connective tissue disorder characterized by a deficiency of lysyl hydroxylase due to mutations in PLOD1. We describe a mutation analysis strategy for the PLOD1 gene using either cDNA or gDNA or a combination thereof, which allows for reliable, time-effective and efficient mutation detection in patients with EDS VIA. We report the results obtained in 9 index patients from 12 unrelated families: three patients were homozygous for three novel mutations (p.Ile454IlefsX2, p.Ala667Thr, and p.His706Arg), four patients were homozygous for the common duplication of exons 10-16, one patient was compound heterozygous for the common duplication and p.Ile454IlefsX2, and one patient was homozygous for p.Arg319X.
