PJVK and deafness: To our knowledge, apart from two variants leading to a truncated PJVK protein (c.113dep, p.Lys41Glufs*8 and c.406C > T, p.Arg92*) (Table 3) in a Moroccan family with a severe to profound deafness, no other PJVK variant has been reported in both the North African and sub-Saharan populations.
