RCV004790070 | SCV005399960 | uncertain significance | Progressive familial intrahepatic cholestasis type 3 | 2021-05-06 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with intrahepatic cholestasis of pregnancy, 3 (ICP-3), low phospholipid-associated cholelithiasis (LPAC) and progressive familial intrahepatic cholestasis, 3 (PFIC) (MIM# 614972, 600803, 602347). (I) 0108 - This gene is associated with both recessive and dominant disease. There is currently no clear genotype-phenotype correlation; however, LPAC and ICP are commonly associated with autosomal dominant inheritance unless the variant leads to a partially functional protein, allowing for recessive inheritance (PMID: 32376413). (I) 0112 - The condition associated with this gene has incomplete penetrance. A single case of an asymptomatic sibling homozygous for a null variant has been reported (PMID: 32376413). (I) 0200 - Variant is predicted to result in a missense amino acid change from leucine to proline. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - Multiple alternative amino acid changes at the same position have been observed in gnomAD (highest allele count: 205 heterozygotes, 2 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated ABC transmembrane type 1-1 (Uniprot). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1102 - Strong phenotype match for this individual. (SP) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
