Genes affected

TGFBI (HGNC:11771): (transforming growth factor beta induced) This gene encodes an RGD-containing protein that binds to type I, II and IV collagens. The RGD motif is found in many extracellular matrix proteins modulating cell adhesion and serves as a ligand recognition sequence for several integrins. This protein plays a role in cell-collagen interactions and may be involved in endochondrial bone formation in cartilage. The protein is induced by transforming growth factor-beta and acts to inhibit cell adhesion. Mutations in this gene are associated with multiple types of corneal dystrophy.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM1

In a domain FAS1 1 (size 133) in uniprot entity BGH3_HUMAN there are 4 pathogenic changes around while only 1 benign (80%) in NM_000358.3

BP4

Computational evidence support a benign effect (MetaRNN=0.23150992).

BS2

High AC in GnomAd4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
