PURPOSE Copy number variants have emerged as a major cause of human disease such as autism and intellectual disabilities. Because copy number variants are common in normal individuals, determining the functional and clinical significance of rare copy number variants in patients remains challenging. The adoption of whole-genome chromosomal microarray(More)
Mutations in GJB2 encoding the gap junction protein connexin-26 (Cx26) have been established as the basis of autosomal recessive non-syndromic hearing loss. The involvement of GJB2 in autosomal dominant deafness has also been proposed, although the putative mutation identified in one family with both deafness and palmoplantar keratoderma has recently been(More)
Atopic disease, including atopic dermatitis (eczema), allergy and asthma, has increased in frequency in recent decades and now affects approximately 20% of the population in the developed world. Twin and family studies have shown that predisposition to atopic disease is highly heritable. Although most genetic studies have focused on immunological(More)
We recently mapped the disease locus for severe autosomal recessive lamellar ichthyosis (LI) to chromosome 14q11 and showed complete linkage with TGM1, the gene encoding transglutaminase 1. We have now identified point mutations in TGM1 in two of the multiplex LI families used in the linkage study. Each nucleotide change causes a non-conservative amino acid(More)
Genes of three protein families, which are in part specifically expressed in the course of terminal differentiation of human epidermis, have previously been mapped to chromosome 1q21. Here we show that these genes are physically linked within 2.05 Mb of DNA. The order is calpactin I light chain, trichohyalin, profilaggrin, involucrin/small proline-rich(More)
Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by oculocutaneous albinism and a storage pool deficiency due to an absence of platelet dense bodies. Lysosomal ceroid lipofuscinosis, pulmonary fibrosis and granulomatous colitis are occasional manifestations of the disease. HPS occurs with a frequency of one in 1800 in(More)
PURPOSE Mutations in the transcription factor IRF6 cause allelic autosomal dominant clefting syndromes, Van der Woude syndrome, and popliteal pterygium syndrome. We compared the distribution of IRF6 coding and splice-site mutations from 549 families with Van der Woude syndrome or popliteal pterygium syndrome with that of variants from the 1000 Genomes and(More)
Many genetic defects are known to cause abnormal development of the coat in mice. Hair keratin genes would seem to be particularly promising candidates among the potential targets of these mutations in mice and of inherited hair-related abnormalities in humans as well. We used specific probes from cloned and sequenced mouse hair keratin cDNAs (MHKA-2,(More)
PURPOSE Interferon regulatory factor 6 encodes a member of the IRF family of transcription factors. Mutations in interferon regulatory factor 6 cause Van der Woude and popliteal pterygium syndrome, two related orofacial clefting disorders. Here, we compared and contrasted the frequency and distribution of exonic mutations in interferon regulatory factor 6(More)
