His team has identified drug candidates for hereditary disorders caused by nonsense mutations and is particularly focused on rare skin diseases.
Desmoplastic melanoma is a rare subtype of melanoma characterized by dense fibrous stroma, resistance to chemotherapy and a lack of actionable driver mutations, and is highly associated with ultraviolet light-induced DNA damage1.
Cerebrotendinous xanthomatosis is a progressive neurodegenerative storage disease caused by recessive CYP27A1 mutations and is characterized by abnormal deposition of cholestanol and cholesterol in multiple tissues, including the lens and brain.
Here we show that a peculiar form of β-amyloid that is devoid of the first ten amino acids accumulates in the brains of patients carrying presenilin-1 mutations, and is more abundant than in subjects affected by the other types of Alzheimer's.
Similar to the WT receptor, GR K442A R447andnd GR S425G associated with the p65/RelA subunit of NF-κB when co-expressed (Fig. 1d and Supplementary Figure 3b), indicating that protein protein interaction between GR and NF-κB is not disrupted by the mutations and is not sufficient for GR-mediated transcriptional repression.
With regard to the leptin gene, we note that pathological leptin deficiency occurs only in subjects with biallelic mutations and is therefore much less frequent than, e.g., MC4R mutation (which can lead also in the heterozygous status to disease manifestation).
The E-cadherin gene has been postulated as a possible tumour gene suppressor with a large number of possible mutations and is also found in ILC and low-grade DCIS [20].
The counting technique used by Knudsen & Hein is likely to under-count certain mutations, and is an approximation to a true Maximum Likelihood (ML) estimate.
We demonstrate that LKB1Ser428 residue is constitutively phosphorylated in cells harboring BRAFV600E activating mutations, and is found frequently phosphorylated in mouse tumor samples with an increased receptor tyrosine kinase activity suggesting a functional connection between BRAF oncogenic pathway and LKB1.
N-Ethyl-N-nitrosourea (ENU) mutagenesis has been widely used to create a large number of germline point mutations, and is a powerful tool for creating disease models [10].
Genetic haplotyping is accurate but will have errors resulting from de novo mutations, and is particularly unreliable for cancer genomes.
