Bardet-Biedl syndrome is an autosomal recessive disorder characterized by polydactyly, obesity, hypogonadism, retinitis pigmentosa, renal anomalies and mental retardation. Clinical heterogeneity is quite marked both within and between families. Linkage has been reported between Bardet-Biedl syndrome and the D16408 marker in chromosomal region 16q21 in an extended Bedouin kindred and, more recently, in a subset of 17 out of 31 families using the PYGM/D11S913 markers in chromosomal region 11q13. We have analyzed linkage to the 16q21 and 11q13 regions and used markers covering chromosomes 2, 3, 17 and 18 in a set of 26 Bardet-Biedl families, each containing at least two affected individuals, with a total of 57 affected members. Evidence of linkage to the D11S527 locus has been identified assuming linkage homogeneity with a lod score of 2.72 at a recombination fraction of 0.11 (95% limits 0.03-0.25).
