The results of genetic sequencing. Two mutations were identified in COG5, (A) c.1290C > A (p.Y430X) and (B) c.2077A > C (p.T693P). (C,D) The father of the proband carried mutation c.1290C > A (p.Y430X), and her mother carried c.2077A > C (p.T693P). The compound-heterozygous mutations in the proband were inherited from her parents. (E) Thr693 is highly conserved across species and located in a highly conserved region. (F) Expression levels of COG5 (93 kDa), small band (around 45 kDa) and GAPDH (Reference, 35 kDa) were shown by western blotting. (G) Quantification of the protein levels. The expression level of COG5 proteins was lower in the patient compared with control. A unknown small band appeared in the patient’s sample but control.
