Comment on list classification: Promoting this gene from red to amber, but with a recommendation for green rating following GMS review. Liver failure could lead to paediatric ITU admission and so thought appropriate for this panel.Created: 27 Jan 2021, 4:28 p.m. | Last Modified: 27 Jan 2021, 4:28 p.m.

Associated with Infantile liver failure syndrome 3 #618641 (AR) in OMIM. Probable association with Infantile-Onset Recurrent Acute Liver Failure and Skeletal Abnormalities in Gene2Phenotype.
PMID:31204009 - Cousin et al 2019 - describe 3 unrelated children with recurrent acute liver failure (RALF) and skeletal abnormalities who were found by WES to have compound heterozygous alterations in RINT1. All had splice alterations at the same position (c.1333+1G>A or G>T) together with a missense (p.Ala368Thr or p.Leu370Pro) or in-frame deletion (p.Val618_Lys619del). One variant was inherited from each parent. 2 of the 3 children had short stature. Imaging showed that they had abnormalities affecting the vertebrae and pelvis. Studies on patient dermal fibroblasts showed that the splice-variant results in skipping of exon 9 leading to an out-of-frame product and nonsense-mediated transcript decay and that there was decreased RINT1 protein levels, abnormal Golgi morphology, and impaired autophagic flux compared to control fibroblasts.
