Amber List (moderate evidence)

LAS1L (LAS1 like, ribosome biogenesis factor)
EnsemblGeneIds (GRCh38): ENSG00000001497
EnsemblGeneIds (GRCh37): ENSG00000001497

5 reviews

Ivone Leong (Genomics England Curator)

Comment on list classification: Based on the expert reviews and available evidence, this gene has been promoted from Red to Amber. This gene is listed in OMIM and Gene2Phenotype with a relevant phenotype. In Gene2Phenotype it has been classified as probable course for the phenotype. As the ID severity in the second case in (PMID: 25644381) is unknown and the variant in 1 case reported by (PMID: 26358559) is predicted to be benign. Until there is further evidence this gene has been given an Amber rating.

Variants in this GENE are reported as part of current diagnostic practice

Eleanor Williams (Genomics England Curator)

Comment on list classification: Candidate gene from Grozeva et al, 2015 but not listed as a gene with likely pathogenic LoF or missense variants. In OMIM this gene is associated with Wilson-Turner syndrome (MIM:309585). Evidence is from Hu et al 2016 (PMID: 25644381). Males in two families with ID (one family with mild to moderate ID the other family with unspecified severity) and different likely causative missense variants in the LAS1L gene. Hackmann et al 2016 (PMID: 26358559) report 1 case where patient with a tentative diagnosis of Lujan-Fryns syndrome has variant in LAS1L but this is predicted to be benign.

Red List (low evidence)

Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)

Panel promoted to version 2.0

Ellen McDonagh (Genomics England Curator)

12.03.2018: Due to major updates completed (Phase 1, 2 and 3), this panel was promoted to Version 2 in order to reflect the major updates since November 2017 which have resulted in reviews for 836 genes added by Genomics England Curators and the Clinical Team, 130 new Green genes added to the interpretation pipeline (from 751 to 881 Green genes), and the gene total has increased from 1879 to 1927.
