In addition to these, KIAA0753 variants were recently described in seven patients with Jeune asphyxiating thoracic dystrophy (ATD) (two first cousins, one unrelated patient and one fetus), Joubert syndrome (two siblings) and orofaciodigital syndrome type 6 (one patient).
We identified the causative gene in 94% of the families; 126 (27 novel) unique potentially pathogenic variants were found in 20 genes, including KIAA0753 and CELSR2, which had not previously been associated with JS.
OFIP/KIAA0753 forms a complex with OFD1 and FOR20 at pericentriolar satellites and centrosomes and is mutated in one individual with oral-facial-digital syndrome.
