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 GeneticsJun 16, 2024The c.428G>C (p.G143A) alteration is located in exon 2 (coding exon 1) of the FBLN2 gene. This alteration results from a G to C substitution at nucleotide position 428, causing the glycine (G) at amino acid position 143 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
