Variant summary

Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PS3PP3_StrongPP5_Very_Strong

The NM_000392.5(ABCC2):c.3517A>T(p.Ile1173Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000013 in 1,614,090 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000359803: Expression studies indicated that the p.Ile1173Phe variant resulted in impaired transport activity of the ABCC2 protein, expression of the variant protein was low, and the variant protein itself mislocated to the endoplasmic reticulum (Mor-Cohen et al. 2001)." and additional evidence is available in ClinVar.

Genes affected

ABCC2 (HGNC:53): (ATP binding cassette subfamily C member 2) The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily which is involved in multi-drug resistance. This protein is expressed in the canalicular (apical) part of the hepatocyte and functions in biliary transport. Substrates include anticancer drugs such as vinblastine; therefore, this protein appears to contribute to drug resistance in mammalian cells. Several different mutations in this gene have been observed in patients with Dubin-Johnson syndrome (DJS), an autosomal recessive disorder characterized by conjugated hyperbilirubinemia.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000359803: Expression studies indicated that the p.Ile1173Phe variant resulted in impaired transport activity of the ABCC2 protein, expression of the variant protein was low, and the variant protein itself mislocated to the endoplasmic reticulum (Mor-Cohen et al. 2001).; SCV003263529: Experimental studies have shown that this missense change affects ABCC2 function (PMID: 11477083, 12388192, 22290738).

PP3

MetaRNN computational evidence supports a deleterious effect, 0.988

PP5

Variant 10-99836193-A-T is Pathogenic according to our data. Variant chr10-99836193-A-T is described in ClinVar as Pathogenic. ClinVar VariationId is 8418.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
