ERCC1 variants cause a hepatorenal syndrome
A new study published in European Journal of Human Genetics described biallelic variants in ERCC1, which encodes a multifunctional endonuclease involved in nucleotide excision repair, interstrand crosslink repair, and DNA double-strand break repair. The variants were found among 7 individuals from 5 unrelated families, with progressive cholestatic liver disease, risk of pediatric hepatocellular carcinoma, renal impairment, photosensitivity, growth restriction, and multi-organ failure in older individuals. Various analyses confirmed this gene-disease association and expanded the spectrum of DNA repair disorders with its mutations.
