LongevityMap variant group

Entry Details

Longevity Association
Non-significant
Population
American (Caucasian), French
Study Design
A haplotype-based fine-mapping study was performed in 653 individuals (456 females, >= 98 years, mean age = 100.8 years) and controls (< 50 years, mean age = 38.6 years). Then, the identified haplotype marker was tested in 564 French (472 females, >= 99 years, mean age = 103.1 years) and 564 controls (18- 70 years, mean age = 51.2 years).
Conclusions
Although the association was not replicated in French cohort, there was evidence for statistical distortion in the form of Hardy–Weinberg disequilibrium.

Gene details

HGNC symbol
MTTP
Aliases
ABL; MTP 
Common name
microsomal triglyceride transfer protein 
Description
MTP encodes the large subunit of the heterodimeric microsomal triglyceride transfer protein. Protein disulfide isomerase (PDI) completes the heterodimeric microsomal triglyceride transfer protein, which has been shown to play a central role in lipoprotein assembly. Mutations in MTP can cause abetalipoproteinemia. [provided by RefSeq, Jul 2008]
