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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.695T>C (p.L232P) alteration is located in exon 2 (coding exon 1) of the FBLN2 gene. This alteration results from a T to C substitution at nucleotide position 695, causing the leucine (L) at amino acid position 232 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
