LRRTM3 polymorphisms may play a role in the pathogenesis of late-onset Alzheimer's disease (LOAD) in a Northern Han Chinese population.
Title: Association of LRRTM3 polymorphisms with late-onset Alzheimer's disease in Han Chinese.
protein interactions between LRRTM3, APP and BACE1, as well as complex associations between mRNA levels of LRRTM3, CTNNA3, APP and BACE1 in humans might influence APP metabolism and ultimately risk of AD
Title: LRRTM3 interacts with APP and BACE1 and has variants associating with late-onset Alzheimer's disease (LOAD).
LRRTM3 is not an essential regulator of amyloid-beta production in adult mice; there are no differences in genotype between levels of Abeta or Abeta protein precursor C-terminal fragments in vivo.
Title: LRRTM3 is dispensable for amyloid-β production in mice.
One single-nucleotide polymorphism in the promoter region and a block of 4 single-nucleotide polymorphisms in intron 2 were associated with AD in the National Institute on Aging Late-Onset Alzheimer's Disease data set or the Caribbean Hispanic data set.
Title: Effect of genetic variation in LRRTM3 on risk of Alzheimer disease.
Apart from the complexity of its regulation, alterations in both CTNNA3 and LRTMM3 are implicated in human disease.

Data suggest that LRRTM3 is a functional and positional candidate gene for Alzheimer disease, and, given its receptor-like structure and restricted expression, a potential therapeutic target.
Title: LRRTM3 promotes processing of amyloid-precursor protein by BACE1 and is a positional candidate gene for late-onset Alzheimer's disease.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks two exons and contains two alternate 5' exons, compared to variant 1. This variant is represented as non-coding because it lacks a large portion of the coding region, including the translational start codon, found in variant 1.
