N2 - The murine limb deformity (ld) locus resides on mouse chromosome 2 and gives rise to a recessively inherited, characteristic limb deformity/renal aplasia phenotype. In this locus in the mouse, a gene, termed the "formin" gene, has been identified which encodes an array of differentially processed transcripts in both adult and embryonic tissues. A set of these transcripts are disrupted in independent mutant mouse ld alleles. We wish to report the isolation of a human genomic clone which is homologous to the mouse formin gene by virtue of sequence comparison and expression of conserved exons. Among human fetal tissues analyzed, the kidney appears to be a major site of expression. This human gene, LD, maps to chromosome 15q11→qter in mouse human somatic cell hybrids and, specifically, to 15q13→q14 by chromosomal in situ hybridization. This localization establishes both LD and β2-microglobulin as syntenic genes on mouse chromosome 2 and human chromosome 15 and implies the interspecies conservation of the region between them. In addition, we identify in the human locus two frequently occurring DNA polymorphisms which can be used to test the linkage of LD to known human dysmorphoses.
