van Steensel M, van Geel M, Steijlen P. A new type of erythrokeratoderma. Br J Dermatol. 2005;152:155-8 pubmed
..Hence we propose that we have delineated a novel type of keratoderma. ..

..Our finding suggest that careful audiological evaluation of patients suffering from Clouston-syndrome-like phenotypes is warranted and expand the spectrum of connexin26-associated disease. ..

. A 2-bp deletion in the GJA1 gene is associated with oculo-dento-digital dysplasia with palmoplantar keratoderma. Am J Med Genet A. 2005;132A:171-4 pubmed
..This is predicted to lead to the production of a slightly truncated protein with 46 incorrect amino acids in the C-terminal cytoplasmic loop (C260fsX307). This novel mutation may explain the presence of skin symptoms. ..

. Recurring HRAS mutation G12S in Dutch patients with Costello syndrome. Exp Dermatol. 2006;15:731-4 pubmed
..To our knowledge, our patients are the first Dutch to be analysed. The syndrome seems to be genetically homogeneous. We discuss the pertinent nosology of the syndrome. ..

. Novel mutations in the BHD gene and absence of loss of heterozygosity in fibrofolliculomas of Birt-Hogg-Dubé patients. J Invest Dermatol. 2007;127:588-93 pubmed
..Renal microscopic oncocytosis in BHD is considered as a precursor to malignant kidney tumors and may likewise be the result of haplo-insufficiency, with somatic second-hit mutations or LOH giving rise to malignancy later in life...
van Steensel M, van Geel M, Parren L, Schrander Stumpel C, Marcus Soekarman D. Shprintzen-Goldberg syndrome associated with a novel missense mutation in TGFBR2. Exp Dermatol. 2008;17:362-5 pubmed
..It has been suggested that these conditions represent a phenotypical spectrum associated with aberrant TGF-beta signalling. In support of this notion, we found a novel TGFBR2 missense mutation in a patient with features of SGS. ..
