Eur J Hum Genet 13:1268-74. 2005..20 Mb. Since the same phenotype appears not to be linked to this locus in a German family, we predict genetic heterogeneity in zygodactyly and propose to designate the 3p21.31 locus as ZD1 (i.e., zygodactyly 1)...

- Spectrum of the acrocallosal syndromeRainer Koenig
Department of Human Genetics, Johann Wolfgang Goethe University, Frankfurt, Germany
Am J Med Genet 108:7-11. 2002..Cranial cysts were also seen in 10/34 published cases of ACS. Thus, intracerebral cysts are a common finding in ACS and may serve in differentiating ACS from Greig cephalopolysyndactyly syndrome...
- IFAP syndrome is caused by deficiency in MBTPS2, an intramembrane zinc metalloprotease essential for cholesterol homeostasis and ER stress responseFrank Oeffner
Department of Human Genetics, Philipps Universitat, Marburg 35037, Germany
Am J Hum Genet 84:459-67. 2009..Our findings indicate that the phenotypic expression of IFAP syndrome is quantitatively related to a reduced function of a key cellular regulatory system affecting cholesterol homeostasis and ability to cope with ER stress...

- Human intronic enhancers control distinct sub-domains of Gli3 expression during mouse CNS and limb developmentAmir A Abbasi
Department of Human Genetics, Philipps Universitat Marburg, 35037 Marburg, Germany
BMC Dev Biol 10:44. 2010..From these studies it has emerged, that Gli3 expression must be subject to a tight spatiotemporal regulation. However, the genetic mechanisms and the cis-acting elements controlling the expression of Gli3 remained largely unknown...
