This gene is associated with a phenotype in OMIM and Gene2Phenotype. Currently, there is not enough evidence to support a gene-disease association. It is recommended that this gene should be demoted to Amber/Red at the next review.Created: 16 Apr 2021, 7:52 a.m. | Last Modified: 16 Apr 2021, 7:52 a.m.
