Comment on list classification: De novo terminating variants clustered in the C-terminus of the protein have been reported in six unrelated families all with a distinct class of dominantly-acting heterozygous variants in hnRNPA2B1 with a unique clinical phenotype of early childhood-onset progressive muscle weakness, ophthalmoplegia, ptosis, dysphagia, and variable degrees of respiratory insufficiency but no dementia (https://www.nmd-journal.com/article/S0960-8966(20)30203-0/fulltext). This source is a meeting abstract an there is no peer reviewed source at this time.
There is enough evidence for this gene to be green, but GMS opinion is required to confirm this.Created: 12 Jan 2021, 3:08 p.m. | Last Modified: 28 Jan 2021, 5:58 p.m.

de novo mutations in this gene have now been identified in at least 6 unrelated families. these findings have been presented at the world muscle society congress 2020 by the group of Carsten Bonnemann. a full publication is currently in progress. for more details see https://www.nmd-journal.com/article/S0960-8966(20)30203-0/fulltextCreated: 8 Dec 2020, 2:24 p.m. | Last Modified: 8 Dec 2020, 2:24 p.m.
