Elvis Twumasi Aboagye delivers a powerful plenary at #WRC2025, chaired by Frederica Partey and Prof. Osbourne Quaye. He presents on the discovery of a bi-allelic MARVELD2 variant linked to non-syndromic hearing loss in a Ghanaian family. Using whole exome sequencing, his team identified a novel frameshift mutation affecting auditory cell function. He highlights the wider impact of undiagnosed hearing disorders on education and employment, especially where early intervention is lacking. Cellular assays showed reduced protein expression, mislocalization, and cytoskeletal disruption — pointing to impaired auditory cell integrity.
