✦ Synopsis


From a human-Chinese hamster somatic cell hybrid a clone was derived containing chromosome 13 in duplicate as its only human material. This clone was used to construct a human chromosome 13-specific recombinant DNA-library. Overlapping Sau3AI DNA sequences (11.9-17.2 kb) from the cell hybrid were inserted into the lambda phage vector EMBL4. From eleven recombinants having a human insert thirteen putative unique DNA sequences were isolated and cloned into the plasmid vector pBR329. A human-mouse hybrid containing a human chromosome 13 with a deletion of 13q14 and lacking its undeleted homologue was constructed to be used in a selection procedure for DNA sequences belonging to band q14. Three probes originating from two different phages were assigned to 13q14 because they did not hybridise to DNA from this cell hybrid. One of these 13q14 probes detects a low frequency (2/44) MspI restriction fragment length polymorphism. The probes are now being used for screening a cosmid library to find adjacent polymorphic sequences with a RFLP information content suitable for application in the diagnosis of hereditary retinoblastoma.

We report a large Italian pedigree in which five out of six males are affected by a syndrome, following an X-linked inheritance pattern, characterized by ichthyosis, hypogonadotropic hypogonadism, and anosmia. The concurrence of features of X-linked ichthyosis (XLI) with those of Kallmann syndrome,
