“…We performed cosegregation and homozygosity analysis with microsatellite markers corresponding to candidate genes involved in the related phenotype. These included MSX1 (MIM 142983) at 4p16.1-p16.3 (D4S412, D4S2925, D4S2935, D4S2285) (Ivens et al 1990), MSX2 (MIM 123101) at 5q34-q35 (D5S529, D5S2050, D5S625, D5S2108) (Jabs et al 1993), epidermal growth factor (EGF, MIM 131530) at 4q25-27 (D4S1564, D4S193, D4S1611, D4S402) (Morton et al 1986), epidermal growth factor receptor (EGFR, MIM 131550) at 7p12.1-p12.3 (D7S2561, D7S674, D7S506, D7S2475) (Haley et al 1987), ectodermal dysplasia type 1 (ED1, MIM 305100) (MIM 300451) at Xq12-q13.1 (DXS7132, DXS1216, DXS8031, DXS453) (Srivastava et al 1996), ectodermal dysplasia type 2 (ED2, MIM 129500) gene GJB6 (MIM 604418) at 13q12.11-q12.3 (D13S1316, D13S175, D13S633, D13S250, D13S787) (Kelley et al 1999), ectodermal dysplasia type 3 (ED3, MIM 224900), ectodysplasin1 anhidrotic receptor (EDAR, MIM 604095) at 2q11-q13 (D2S1343, D2S2954, D2S340, D2S1889, D2S1893, D2S1891) (Monreal et al 1999), and ectodermal dysplasia type 4 (ED4, MIM 225000) PVRL1 (MIM 600644) at 11q23-q24 (D11S1885, D11S4171, D11S4129, D11S924, D11S1299) (Lopez et al 1995).…”
