Illumina Laboratory Services, Illumina RCV004528106 SCV000915898 uncertain significance UGT1A1-related disorder 2018-11-21 criteria provided, single submitter clinical testing The UGT1A1 c.1198A>G (p.Asn400Asp) missense variant has been reported in one study and is found in a total of three patients including one in a homozygous state with Crigler-Najjar syndrome type II (CN-II) and two in a heterozygous state with Gilbert syndrome (Labrune et al. 2002). The patient with CN-II carried a second homozygous variant in the TATA box promoter region identified as UGT1A1*37. The p.Asn400Asp variant was absent from 50 control chromosomes and is reported at a frequency of 0.00007 in the European (non-Finnish) population of the Exome Aggregation Consortium. Based on the limited evidence, the p.Asn400Asp variant is classified as a variant of unknown significance but suspicious for pathogenicity for UGT1A1-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
