HADHB encodes mitochondrial trifunctional protein beta subunit. As reviewed by Dmitrijs Rots, there are four unrelated patients reported with biallelic HADHB variants and episodic myopathy.
This gene has been associated with relevant phenotypes in OMIM (MIM #620300), but not in Gene2Phenotype.Created: 8 Jan 2024, 11:01 a.m. | Last Modified: 8 Jan 2024, 11:01 a.m.
