Linkage analysis has been performed on a large South African family of British origin in which 39 persons in 6 generations had early onset Type I autosomal dominant retinitis pigmentosa (ADRP). Tight linkage was excluded between the disease and the D3S47 locus on chromosome 3. This finding is further evidence for genetic heterogeneity in ADRP.
对一个起源于英国的南非大家庭进行了连锁分析,该家族6代中有39人患有早发性常染色体显性遗传性视网膜色素变性(ADRP)。排除了该疾病与3号染色体上D3S47位点之间的紧密连锁。这一发现进一步证明了ADRP存在遗传异质性。
