Green List (high evidence)

Comment on list classification: At least six unrelated families exhibiting a strikingly similar phenotype due to biallelic truncating variants in the NUP188 gene. Only 1/8 individuals survived beyond the first year of life and exhibited severe ID.

It is anticipated that other surviving patients would likely present the same phenotype; however, for now NUP188 will be rated Amber on the ID panel, awaiting further publications to corroborate the relevance of this manifestation.

Associated with Sandestig-Stefanova syndrome in OMIM, but not yet in G2P.

- PMID: 32021605 (2020) - Two unrelated patients with different homozygous nonsense variants of NUP188, c.287dupA, p.Tyr96* and c.337C>T, p.Gln113*, respectively. Authors note strikingly comparable phenotypes including pre- and postnatal microcephaly, trigonocephaly, congenital cataract, microphthalmia, cleft lip and palate or high-arched palate, camptodactyly, ventricular septal defect, and brain MRI anomalies (ventriculomegaly, loss of periventricular white matter, thin corpus callosum, and delayed myelination). Both ultimately died as a result of central respiratory failure at the age of 67 and 140 days, respectively.

- PMID: 32275884 (2020) - Six individuals from four unrelated families with bi-allelic truncating variants in NUP188 and similar phenotypes characterised by prenatal-onset ventriculomegaly or suspected brain malformation (4/6), congenital cataracts (4/6), congenital heart defects (5/5), hypotonia (5/6), brain MRI abnormalities (6/6) including ventriculomegaly loss of white-matter, hypoplastic corpus callosum, and delayed myelination. Progressive microcephaly consistent with a neurodegenerative process was noted in at least 3 cases. All six patients died of respiratory failure or respiratory-related illness: five within the first seven months of life; and the sixth at 2 years and 7 months, who also has severe ID and was non-ambulatory.

Red List (low evidence)

The gene was present in the current panel with red rating, though with no reviews.

In Pubmed there are no publications concerning a link with ID. One publication (PMID: 21282601) reports on a 9q34.11 148 kb duplication spanning NUP188 as well as few other genes found in an individual with d-TGA (dextro-transposition of great arteries). Eventual other phenotypes are not commented on. A further publication (PMID: 28611029) reports on an individual heterozygous for a splice-site SNV but only cardiovascular phenotype is commented on again (mitral valve prolapse - variant : NM_015354.2:c.4737+1G>T).

There are no publications when searching for the alternative gene symbol (KIAA1069), either.

There is no associated phenotype in OMIM or G2P.
The gene is not included in the SysID and SFARI databases.

The denovo-db lists 4 non-synonymous de novo variants in individuals with autism or mixed phenotype.
[ http://denovo-db.gs.washington.edu/denovo-db/QueryVariantServlet?searchBy=Gene&target=NUP188 ]

In Decipher, all CNVs encompassing NUP188 span also other proximal genes. There are no relevant SNVs.

The gene is part of the ID panel of VCGS (TGW024_genelist_V3 - Oct2018) which was also listed as source in the current panel.

Overall, red rating (or removal from the current panel) seems appropriate.
