Genes affected

SERPINF1 (HGNC:8824): (serpin family F member 1) This gene encodes a member of the serpin family that does not display the serine protease inhibitory activity shown by many of the other serpin proteins. The encoded protein is secreted and strongly inhibits angiogenesis. In addition, this protein is a neurotrophic factor involved in neuronal differentiation in retinoblastoma cells. Mutations in this gene were found in individuals with osteogenesis imperfecta, type VI. [provided by RefSeq, Aug 2016]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-1769884-GGT-G is Pathogenic according to our data. Variant chr17-1769884-GGT-G is described in ClinVar as [Pathogenic]. Clinvar id is 41892.Status of the report is no_assertion_criteria_provided, 0 stars.
