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: Pathogenic. The variant received 11 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

PM5

Other missense variant is known to change same aminoacid residue: Variant chr5-136046407-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 7872.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP5

Variant 5-136046407-G-A is Pathogenic according to our data. Variant chr5-136046407-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 7869.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAd4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
