DLEC1 gene related symptoms and diseases

Description

Lung cancer is the leading cause of cancer deaths in the U.S. and worldwide. The 2 major forms of lung cancer are nonsmall cell lung cancer and small cell lung cancer (see {182280}), which account for 85% and 15% of all lung cancers, respectively. Nonsmall cell lung cancer can be divided into 3 major histologic subtypes: squamous cell carcinoma, adenocarcinoma, and large cell lung cancer. Cigarette smoking causes all types of lung cancer, but it is most strongly linked with small cell lung cancer and squamous cell carcinoma. Adenocarcinoma is the most common type in patients who have never smoked. Nonsmall cell lung cancer is often diagnosed at an advanced stage and has a poor prognosis (summary by Herbst et al., 2008).

Description

Esophageal cancer, particularly esophageal squamous cell carcinoma (ESCC), is one of the most common cancers worldwide. Both environmental and genetic risk factors play a role in the pathogenesis of the disorder. In Europe and North America, heavy smoking, alcohol consumption, and increased body mass index (BMI) are the main environmental risk factors. In contrast, the particularly high incidence of ESCC in some areas of China, central Asia, and southern Africa is associated with nutritional deficiencies, high intake of nitrosamine-rich or pickled vegetables, and low socioeconomic status; smoking, alcohol consumption, and BMI play a lesser role in these populations. There is a tendency for familial aggregation of ESCC in high-risk geographic areas, suggesting a genetic component to increased susceptibility. Gastric cardia adenocarcinoma is another common type of cancer in China that shows similarities to ESCC in terms of geographic distribution and environmental risk factors (summary by Wang et al., 2010 and Abnet et al., 2010). Genetic Heterogeneity of Susceptibility to Esophageal CancerSee a variant in the ADH1B gene ({103720.0001}) for discussion of a possible genetic association with protection against squamous cell aerodigestive tract cancer, including esophageal cancer, in alcohol drinkers. See a variant in the ALDH2 gene ({100650.0001}) for discussion of a possible genetic association with increased risk for esophageal cancer in alcohol drinkers due to interaction between variants in the ADH1B and ALDH2 genes.See the S100A14 gene (OMIM ) on chromosome 1q21 for a discussion of a possible association between variation in that gene and susceptibility to esophageal squamous cell carcinoma among smokers. Genetic Heterogeneity of Somatic Mutations in Esophageal CancerSomatic mutations in several different genes have been found in esophageal cancer tissue. These genes include TP53 (OMIM ), CDKN2A (OMIM ), DEC1 (OMIM ), DCC (OMIM ), DLEC1 (OMIM ), TGFBR2 (OMIM ), LZTS1 (OMIM ), RNF6 (OMIM ), WWOX (OMIM ), APC (OMIM ), and RUNX3 (OMIM ).

Alternate names

SQUAMOUS CELL CARCINOMA OF THE ESOPHAGUS Is also known as escc, esophageal epidermoid carcinoma, esophageal squamous cell carcinoma

Description

Esophageal squamous cell carcinoma (ESCC) is a type of esophageal carcinoma (EC; see this term) that can affect any part of the esophagus, but is usually located in the upper or middle third.

Most common symptoms of SQUAMOUS CELL CARCINOMA OF THE ESOPHAGUS

• Feeding difficulties in infancy
• Cough
• Nausea and vomiting
• Lymphadenopathy
• Chest pain
