Across a selection of available literature, the c.890A>G (p.Glu297Gly) variant has been identified in a homozygous state in at least 16 familial intrahepatic cholestasis patients, in a compound heterozygous state in 27 patients, and in a heterozygous state in four patients in whom a second variant was not identified (Strautnieks et al. 1998; Strautnieks et al. 2008; Arnell et al. 2008). The p.Glu297Gly variant was found in a heterozygous state in one of 250 controls and is reported at a frequency of 0.00049 in the European (Non-Finnish) population of the Exome Aggregation Consortium. In vitro functional studies demonstrated that the variant destroys a cryptic splice site, leading to approximately 50% of wild type splicing, and disrupts the processing and trafficking of the ABCB11 protein (Hayashi et al. 2005; Byrne et al. 2009). Based on the collective evidence, the p.Glu297Gly variant is classified as pathogenic for familial intrahepatic cholestasis. (less)

This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 297 of the ABCB11 protein (p.Glu297Gly). This variant is present in population databases (rs11568372, gnomAD 0.04%). This missense change has been observed in individuals with progressive familial intrahepatic cholestasis (PMID: 9806540, 19101985). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 6590). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ABCB11 protein function. Experimental studies have shown that this missense change affects ABCB11 function (PMID: 12370274, 17855769, 19101985). For these reasons, this variant has been classified as Pathogenic. (less)

The ABCB11 c.890A>G variant is predicted to result in the amino acid substitution p.Glu297Gly. This variant has been reported to be pathogenic for intrahepatic cholestasis due to protein misfolding (Strautnieks et al. 1998. PubMed ID: 9806540; Strautnieks et al. 2008. PubMed ID: 18395098; Arnell et al. 2010. PubMed ID: 20683202; Wang et al. 2002. PubMed ID: 12370274). This variant is reported in 0.044% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. (less)

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
