A gene for blepharophimosis-ptosis-epicanthus inversus syndrome maps to chromosome 3q23

Hum Genet. 1995 Aug;96(2):213-5. doi: 10.1007/BF00207381.


Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant malformation of the eyelids that may severely impair visual function. Chromosomal aberrations involving chromosomes 3q23, 3p25 and 7p34 have been reported in BPES but the disease gene has not been hitherto localized by linkage analysis. We have mapped a gene for BPES to chromosome 3q23 in a large French pedigree (Zmax = 4.62 at Theta = 0 for probe AFM 182yc5 at locus D3S1549). The best estimate for the location of the disease gene is at locus D3S1549, between the loci D3S1292 and D3S1555 (maximum lod score of 5.10).
