COL5A1 exon 14 splice acceptor mutation causes a functional null allele, haploinsufficiency of alpha 1(V) and abnormal heterotypic interstitial fibrils in Ehlers-Danlos syndrome II.

Abstract excerpt

We studied four affected individuals from a family of three generations with Ehlers-Danlos Syndrome II. Type V collagen transcripts of affected individuals were screened by reverse transcriptase-polymerase chain reaction. Amplification of the exon 9-28 region of alpha1(V) yielded normal and larger products from the proband. Sequencing of cDNA revealed a 100-base pair insertion from the 3'-end of intron 13 between...
