Paediatric disorders - additional genes
Gene: TOR1AIP1
The rating of this gene has been updated to Green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.Created: 11 Oct 2023, 1:16 p.m. | Last Modified: 11 Oct 2023, 1:16 p.m.
Panel Version: 3.5
Gene was initially added to the Cardiomyopathy panel; however, after NHS GMS review it was determined that R27 (congenital malformation/syndromic) panel is more appropriate. Therefore adding here with the recommendation of upgrading to Green status at the next review.

Associated with relevant phenotype in OMIM, but currently not in Gene2Phenotype.
At least 15 affected individuals from 10 families with biallelic variants in this gene. Of these, 7 individuals (5 families) reported in PMID:30723199 harbour the same founder variant presenting a very similar phenotype, and are therefore considered collectively here. Patients present a severe multisystem phenotype with muscular dystrophy being the prominent feature observed in at least one case in each family, but additional common features also include joint contractures (4 fam), dilated cardiomyopathy (4 fam), developmental delay (4 fam), and cataracts (3 fam).
Note that one additional homozygous case has been reported with what is thought to be a discrete phenotype characterised by progressive dystonia, cerebellar atrophy, and dilated cardiomyopathy (PMID: 25425325). Biallelic variants have also been linked to a congenital myasthenic syndrome in two unrelated families (PMID: 33215087; 34164833).
