Targeted gene under study

YIF1B (OMIM #619109) Kaya-Barakat-Masson syndrome (OMIM #619125)


We previously described a severe neurodevelopmental disorder caused by bi-allelic variants in YIF1B (PMID: 32006098, PMID: 34373908). Since then, we have continued to study this new rare syndrome using clinical and functional studies. We are calling for additional affected individuals for our clinical studies, and would also be very interested in affected individuals willing to donate cells for induced pluripotent stem cell based studies.
