We determined the chromosomal location of the mouse gene Stk25, encoding a member of the Ste20/PAK family of serine/threonine kinases, by interspecific backcross analysis. We mapped Stk25 to the central region of mouse chromosome 1 linked to Chrng (formerly Acrg) and En1. This central region of mouse chromosome 1 shares a region of homology with the long arm of human chromosome 2, suggesting that the human homologue of Stk25 would also map to 2q. We proved this prediction of syntenic homology correct by mapping human STK25 to 2q37. Deletion of the 2q37 region has been implicated in the expression of pseudopseudohypoparathyroidism (PPHP), a disease which shares features of the Albright hereditary osteodystrophy (AHO) phenotype. To investigate a pathogenetic relationship between STK25 and PPHP, we carried out fluorescence in situ hybridization (FISH) using an STK25 gene probe and chromosomes from PPHP patients characterized as having small deletions near the distal end of 2q. PPHP patient DNA showed no hybridization to STK25 genomic DNA, indicating that STK25 is contained within the deleted chromosomal region. This finding, in conjunction with previous studies demonstrating the role of Ste20/PAK kinases in heterotrimeric G protein signaling, suggests that STK25 is a positional candidate gene for PPHP.

Deletions of the 2q37 region are associated with a recognizable pattern of MCA/MR so-called the AHO-like syndrome. Brachydactyly is a variable but characteristic feature of this clinical entity. Here we report on five cases of cytogenetically visible de novo deletions of this 2q37 chromosome region. Using FISH, we characterized at the molecular level the breakpoints of these deletions using a set of 15 BACs, PACs and YACs. In four patients, terminal deletions of variable size ranged between 6.2 and 10 Mb. The fifth patient had an interstitial deletion with an AHO-like phenotype including brachydactyly. These findings when compared to previous observations allowed us to narrow down the brachydactyly critical region between BACs RP11-585E12 and RP11-351E10. It contains HDAC4 and STK25 candidate genes loci.
