We found CNV duplications segregating with BD under the highest family-specific linkage peak in two families: one spanning PDZD2 and GOLPH3 (PED_5, hg19/chr5:32109541-32170613bp); the other spanning AMICA1, MPZL3, MPZl2 and CD3E (PED_121, hg19/chr11:118081344-118195313bp) (Supplementary Table S2). The gene discussed is MPZL3; the disease is Behcet disease.
