Genes affected

FLNB (HGNC:3755): (filamin B) This gene encodes a member of the filamin family. The encoded protein interacts with glycoprotein Ib alpha as part of the process to repair vascular injuries. The platelet glycoprotein Ib complex includes glycoprotein Ib alpha, and it binds the actin cytoskeleton. Mutations in this gene have been found in several conditions: atelosteogenesis type 1 and type 3; boomerang dysplasia; autosomal dominant Larsen syndrome; and spondylocarpotarsal synostosis syndrome. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Nov 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

PM1

In a region_of_interest Actin-binding (size 238) in uniprot entity FLNB_HUMAN there are 60 pathogenic changes around while only 5 benign (92%) in NM_001457.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), FLNB. . Gene score misZ 2.1406 (greater than the threshold 3.09). Trascript score misZ 4.529 (greater than threshold 3.09). GenCC has associacion of gene with spondylocarpotarsal synostosis syndrome, atelosteogenesis type I, Larsen syndrome, Boomerang dysplasia, atelosteogenesis type III.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.906
