Fig. 4From: A heterozygous duplication variant of the HOXD13 gene caused synpolydactyly type 1 with variable expressivity in a Chinese familySequence analysis of HOXD13 mutation in the Chinese family. a, Sanger sequencing result of the unaffected member (V-2) done after PCR showing no double peaks. b, Sanger sequencing result of the diseased (V-1) done after PCR showing double peaks at duplication site. c, Sanger sequencing result of the affected member (IV-11) done after PCR showing double peaks at duplication siteBack to article page
