Genes affected

FBLN2 (HGNC:3601): (fibulin 2) This gene encodes an extracellular matrix protein, which belongs to the fibulin family. This protein binds various extracellular ligands and calcium. It may play a role during organ development, in particular, during the differentiation of heart, skeletal and neuronal structures. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.763A>C (p.T255P) alteration is located in exon 2 (coding exon 1) of the FBLN2 gene. This alteration results from a A to C substitution at nucleotide position 763, causing the threonine (T) at amino acid position 255 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
