Intestinal failure or congenital diarrhoea
Gene: AP1S1The rating of this gene has been updated following NHS Genomic Medicine Serviceapproval.Created: 8 Mar 2022, 11:44 a.m. | Last Modified: 8 Mar 2022, 11:44 a.m.

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a phenotype in OMIM but not in Gene2Phenotype.
After discussion with the Genomics England Clinical Team it was decided that it was appropriate to consider all evidence (including the cases that have an intestinal phenotype for this gene - MEDNIK syndrome), therefore, there is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.Created: 4 May 2021, 9:51 a.m. | Last Modified: 4 May 2021, 9:51 a.m.
Panel Version: 1.39
- Established gene-disease association with MEDNIK syndrome
- PMID: 32306098 propose a clinical and genetic expansion for AP1S1-associated disease
- 2 consanguineous families, each carrying a homozygous missense AP1S1 variant
- AP1S1 knockout cell line demonstrated tight-junction and polarity abnormalities that were rescued by WT AP1S1, but not the AP1S1 missense variants.
