Schematic pedigrees of the families with NDP mutations. Arrows indicate probands; open symbols, clinically unaffected; solid symbols, clinically affected; diagonal lines through symbols, deceased; vertical lines in symbols, affected by hearsay; circles inside symbols, asymptomatic for familial exudative vitreoretinopathy; +/−, heterozygous with familial mutation; and −/−, wild type. For the NDP mutations, the nomenclature is based on GenBank NM_012193.2
