Abstract

We have isolated and chromosomally fine-mapped 16 novel genes belonging to the human zinc finger Krüppel family (ZNF131-140, 142, 143, 148, 151, 154, and 155), including 1 of the GLI type (ZNF143) and 3 containing a KRAB (Krüppel-associated box) segment (ZNF133, 136, and 140). Based on their map position, several of these ZNF genes are putative candidate genes for both developmental and malignant disorders: ZNF138, ZNF139, and ZNF143 were localized to 7q11.2, 7q21.3-q22.1, and 11p15.3-p15.4, regions involved in deletions and/or translocations associated with Williams syndrome, split hand and foot disease (SHFD1), and Beckwith-Wiedemann syndrome, respectively. ZNF133 was localized to 20p11.2, close to, but probably distinct from, the region deleted in Alagille syndrome. Zinc finger genes mapping to regions commonly deleted in solid tumors included ZNF132, 134, 135, 137, 154, and 155, all located on 19q13 (thyroid adenoma), and ZNF151, at 1p36.1-p36.2 (neuroblastoma, colon cancer, and other tumors). In addition, several of the ZNFs mapped to regions implicated in recurrent chromosomal rearrangements in hematological malignancies (ZNF139, 7q21.3-q22.1; ZNF148, 3q21-q22; ZNF151, 1p36.1-p36.2). The study indicates that the number of ZNF genes in human is large and that systematic isolation and mapping of ZNF genes is a straightforward approach for the identification of novel candidate disease genes.
