Here, we describe five unrelated individuals with bi-allelic variants in death-associated protein 3 (DAP3), a nuclear gene encoding mitoribosomal small subunit 29 (MRPS29), with variable clinical presentations ranging from Perrault syndrome (sensorineural hearing loss and ovarian insufficiency) to an early childhood neurometabolic phenotype. This evidence concerns the gene DAP3 and Perrault syndrome.
