Genes affected

EFEMP1 (HGNC:3218): (EGF containing fibulin extracellular matrix protein 1) 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. Alternatively spliced transcript variants that encode the same protein have been described.[provided by RefSeq, Nov 2009]

The c.1475C>T (p.S492L) alteration is located in exon 12 (coding exon 10) of the EFEMP1 gene. This alteration results from a C to T substitution at nucleotide position 1475, causing the serine (S) at amino acid position 492 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
