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 GeneticsMay 26, 2023The c.25G>A (p.G9R) alteration is located in exon 2 (coding exon 1) of the FBLN2 gene. This alteration results from a G to A substitution at nucleotide position 25, causing the glycine (G) at amino acid position 9 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
