Genes affected

UTP4 (HGNC:1983): (UTP4 small subunit processome component) This gene encodes a WD40-repeat-containing protein that is localized to the nucleolus. Mutation of this gene causes North American Indian childhood cirrhosis, a severe intrahepatic cholestasis that results in transient neonatal jaundice, and progresses to periportal fibrosis and cirrhosis in childhood and adolescence. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

UTP4 Gene-Disease associations (from GenCC):

• hereditary North American Indian childhood cirrhosis

  Inheritance: AR Classification: SUPPORTIVE, LIMITED Submitted by: Orphanet, G2P
• cirrhosis, familial

  Inheritance: AR Classification: NO_KNOWN Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.13).
• BP7: Synonymous conserved (PhyloP=1.85 with no splicing effect.
