Genes affected

IFITM5 (HGNC:16644): (interferon induced transmembrane protein 5) This gene encodes a membrane protein thought to play a role in bone mineralization. This gene is located on chromosome 11 in a cluster of related genes which are induced by interferon, however, this gene has not been shown to be interferon inducible. A similar gene, located in a gene cluster on mouse chromosome 7, is a member of the interferon-inducible fragilis gene family. The mouse gene encodes a transmembrane protein described as participating in germ cell competence. A mutation in the 5' UTR of this gene has been associated with osteogenesis imperfecta type V (PMID: 22863190, 22863195). [provided by RefSeq, Aug 2012]

A known missense variant, c.119C>T in exon 1 of IFITM5 was observed in a heterozygous state in the proband (Farber et al., 2014). Sanger validation and segregation analysis showed that the variant was present in heterozygous state in the proband and absent in her parents. The variant is absent in gnomAD (v4.1.0) and our in-house database of 3419 exomes. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: IFITM5 c.119C>T (p.Ser40Leu) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 217238 control chromosomes. c.119C>T has been reported in the literature, arising de novo in at-least two individuals affected with Osteogenesis Imperfecta (example, Chandler_2018, Yap_2024). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 29595812, 37799085). ClinVar contains an entry for this variant (Variation ID: 183677). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 40 of the IFITM5 protein (p.Ser40Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with osteogenesis imperfecta (PMID: 24478195, 24519609, 29595812). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 183677). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. -

Review Status:no assertion criteria provided

Collection Method:clinical testing

The IFITM5 c.119C>T variant is predicted to result in the amino acid substitution p.Ser40Leu. This variant is a known pathogenic variant that has been reported as de novo in multiple individuals with osteogenesis imperfecta (Guillén-Navarro et al. 2014. PubMed ID: 24478195; Hoyer-Kuhn et al. 2014. PubMed ID: 24293101; Farber et al. 2014. PubMed ID: 24519609; Rodriguez Celin et al. 2018. PubMed ID: 30039845; Han et al. 2020. PubMed ID: 31994750) and is classified as pathogenic in ClinVar. This variant has not been reported in a large population database, indicating this variant is rare. We interpret this variant to be pathogenic. -
