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]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 04, 2023 | This sequence change creates a premature translational stop signal (p.Val218Glufs*22) in the SERPINF1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SERPINF1 are known to be pathogenic (PMID: 21353196, 21826736). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with osteogenesis imperfecta (PMID: 23054245, 29620724). ClinVar contains an entry for this variant (Variation ID: 41894). For these reasons, this variant has been classified as Pathogenic. - |
