Description

Published functional studies demonstrate a dominant-negative effect as variant protein forms heterodimers with wild type that are deficient at degrading double-stranded DNA and inhibit double-stranded DNA degradation activity of the TREX1 wild type enzyme (Lehtinen et al., 2008; Lee-Kirsch et al., 2007); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 22071149, 23989343, 21808053, 24183309, 17440703, 27943079, 30685859, 18805785, 22829693, 20799324)
