Pedigrees of the proband with FGFR1 and CEP290 mutation. (a) The mutation results in both FGFR1 (A) and CEP290 (B) from all family members. Arrows: mutation sites. (b) Pedigrees of the proband. Circles: females; squares: males; arrows: proband. (c) The domain structures of both FGFR1 (A) and CEP290 (B) with two mutant sites, respectively. SP: signal peptide; HB: binding domain for heparin or heparin sulfate proteoglycan; PLC sites: interaction with PLC gamma; NB: nuclear-binding domain; TK1/2: tyrosine kinase subdomain 1/2; Ig I, Ig II, and Ig III: three Ig-like domains; TM: transmembrane domain.
