Although only 15-0084-004 had been formally diagnosed as being dyslexic, the finding that the reading abilities of 6 of 9 individuals with the deletion were weak or very weak, and two other individuals were in the low-average range (Table S1 in Supplement 1) led us to further assess the potential role of DOCK4 deletions in dyslexia. The gene discussed is DOCK4; the disease is dyslexia.
