PMID:30503519 (Logan et al., 2018) report biallelic variants in POLE in 15 indivs from 12 families (mix of countries). All subjects shared the same intronic variant (c.1686+32C>G) as part of a common haplotype, in combination with different loss-of-function variants in trans. Phenotypically, affected individuals all had IUGR and severe growth failure of prenatal onset. Immunodeficiency in 9 families (either increased susceptibility to infections or documented lymphopenia/ hypogammaglobinemia).Created: 29 Apr 2020, 4:33 p.m. | Last Modified: 29 Apr 2020, 4:33 p.m.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.Created: 20 Apr 2018, 12:25 p.m.
