The region between DXS52 and Factor VIII gene in the human Xq28 chromosomal band contains a G+C-rich isochore to which many genes have been mapped. We report here the isolation and characterization of a transcript mapping about 50 kb telomeric from the
vasopressin
type 2 receptor gene in a 180-kb YACs/cosmid contig containing the
L1CAM
gene at its centromeric end. The determined transcribed sequence from a human fetal brain library is identical to that of the recently identified accessory protein HCFC1 (host cell factor, also called C1) that activates herpes simplex virus VP16 (alpha TIF) transactivator protein for association with the octamer motif-binding protein Oct-1 (Cell 74: 115, 1993). The gene is expressed in a ubiquitous pattern and a larger transcript of approximately 10 kb is present in all the tissues tested, while an alternatively spliced RNA of approximately 8.0 kb is present in muscle and heart tissues. Genomic sequencing allowed us to determine that the sequenced transcript is assembled from 26 exons spread over a relatively small genomic region of approximately 24 kb. This alllowed us to determine that a previously reported cDNA clone arises from the splicing out of an internal portion of exon 8 which does not change the reading frame. All together these results raise the possibility that alternative mRNA processing could partly contribute to the diversity of the polypeptide HCFC1 family in a subset of tissues.

Although long contigs have been assembled in Xq28, the interval between the anonymous probe St14 and the color vision locus is still incompletely defined. We report here that the recently cloned gene for type 2
vasopressin
receptor (V2R) is physically linked to
L1CAM
using YACs and cosmids across about 180 kb of the region. Since it is known that
L1CAM
maps near the color pigment genes, this finding locates V2R in Xq28 in the area where nephrogenic diabetes insipidus (NDI) has been mapped by linkage analysis. The PFGE analysis of the clones positions V2R about 40 kb from the
L1CAM
gene in a region that appears to contain other unknown genes, since at least four putative CpG islands were identified by restriction analysis with rare cutter enzymes.

Mutations in the gene for the human renal-type
vasopressin
receptor (V2R) have recently been identified in patients with nephrogenic diabetes insipidus (NDI). Both V2R and NDI have been independently mapped to Xq28. Using a combination of genetic and physical mapping, we have localized the murine V2r locus to within 100 kb of L1Cam on the mouse X chromosome in a region syntenic with human Xq28. Based on conserved gene order of mouse and human loci in this region, physical mapping using DNA derived from human lymphoblasts has established that the corresponding human loci V2R and
L1CAM
are linked within 210 kb. The efficiency and precision of genetic mapping of V2r and other loci in the mouse suggest that it might be easier to map additional human genes in the mouse first and infer the corresponding human location. More precise physical mapping in man could then be performed using pulsed-field gel electrophoresis and/or yeast artificial chromosomes.

We report on an infant boy with congenital hydrocephalus due to L1 syndrome and polyuria due to diabetes insipidus. We initially believed his excessive urine loss was from central diabetes insipidus and that the cerebral malformation caused a secondary insufficient pituitary
vasopressin
release. However, he failed to respond to treatment with a
vasopressin
analogue, which pointed to nephrogenic diabetes insipidus (NDI). L1 syndrome and X-linked NDI are distinct clinical disorders caused by mutations in the
L1CAM
and AVPR2 genes, respectively, located in adjacent positions in Xq28. In this boy we found a deletion of 61,577 basepairs encompassing the entire
L1CAM
and AVPR2 genes and extending into intron 7 of the ARHGAP4 gene. To our knowledge this is the first description of a patient with a deletion of these three genes. He is the second patient to be described with L1 syndrome and NDI. During follow-up he manifested complications from the hydrocephalus and NDI including global developmental delay and growth failure with low IGF-1 and hypothyroidism.
