Achchuthan Shanmugasundram (Genomics England Curator)

Green List (high evidence)

Comment on list classification: As reviewed by Anna Sarkozy (Great Ormond Street Hospital), biallelic variants in GBE1 has been reported in sufficient number of cases presenting with fetal akinesia/hypokinesia, arthrogryposis multiplex congenita and severe congenital myopathies. Hence, this gene can be promoted to GREEN rating at the next major review.

This gene has been associated with phenotypes in both OMIM and Gene2Phenotype (with 'definitive' rating).

Anna Sarkozy (Great Ormond Street Hospital)

Green List (high evidence)

recessive pathogenic variants in GBE1 gene responsible for GSD IV, have now been identified in a relevant number of patients presenting with severe early onset neuromuscular conditions, ranging from fetal akinesia deformation sequence, to arthrogryposis multiplex congenita and severe forms of congenital onset myopathies. given the major clinical overlap with severe forms of congenital myopathies, this gene should be considered in differential and included in the R81 panel and tested in patients with possible congenital myopathy.
