Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:research

The heterozygous p.Ser31Leu variant in ZNHIT3 was identified by our study, in the compound heterozygous state, along with another likely pathogenic variant, in an individual with PEHO syndrome (PMID: 31048081). This variant has also been reported in 22 additional individuals with PEHO syndrome, segregated with disease in 4 affected relatives from 2 families (PMID: 28335020), which increases the likelihood that the p.Ser31Leu variant is pathogenic. The variant has also been reported as pathogenic by OMIM in ClinVar (Variation ID: 427725). The p.Ser31Leu variant has been identified in 0.476% (119/25006) of European (Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs148890852). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. The p.Ser31Leu is located in a region of ZNHIT3 that is essential to protein folding and stability, suggesting that this variant is in a functional domain and slightly supports pathogenicity (PMID: 28335020). Additionally, animal models in zebrafish and in vitro functional studies have shown that this variant causes PEHO syndrome (PMID: 28335020). However, these types of experiments may not accurately represent biological function. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic.
