This gene encodes a member of the fibulin family of extracellular matrix
glycoproteins. Like all members of this family, the encoded protein contains tandemly repeated epidermal growth factor-like repeats followed by a C-terminus fibulin-type domain. This gene is upregulated in malignant
gliomas and may play a role in the aggressive nature of these tumors. Mutations in this gene are associated with Doyne honeycomb retinal dystrophy and with predisposition to
hernias. Alternatively spliced transcript variants that encode the same protein have been described.[provided by RefSeq, Nov 2009]. This gene spans approximately 18 kb of genomic DNA and consists of 12 exons. Alternative splice patterns in the 5' UTR result in three transcript variants encoding the same
extracellular matrix protein. == Clinical significance ==
