LRRTM1 expression is downregulated maternally in humans. You can help Wikipedia by expanding it. Lay summary — BBC News. Developmental Gene Expression 7. When comparing expression between human and mouse, it seems that there is a striking absence of signal in caudate and putamen in mouse, at least at e15 and in adult.

LRRTM1 is not localized on the plasma membrane. Supplementary Figure S6 lrrtm1 1,K Click here to view. March 6, Last modified: Lack of this gene shows decreased performance in complex visual tasks.

In developing mice, Lrrtm1 was expressed at embryonic day 13 and Integrated resource of protein families, domains and functional sites More GXD’s primary emphasis is on endogenous gene expression during development. Please review our privacy policy. Of a total lrtm1 approximately 35 human genes, only roughly 40 were previously known to be imprinted, and the total number is unlikely to exceed this greatly.

UCSC genome browser More A ruler that provides location information. Replication validity of genetic association studies. Mice homozygous for a knock-out allele exhibit impaired cognitive function and altered hippocampal synapse morphology.

We also showed that LRRTM1 is expressed during the development of specific forebrain structures, and thus could influence neuronal differentiation and connectivity.

Since LRRTM1 appears to underlie the strongest linkage to schizophrenia in the genome, as identified by a meta-analysis of 20 genomewide linkage scans, 16 it is possible that LRRTM1 dysfunction causes a major, common subtype of schizophrenia. LRRTM1, leucine rich repeat transmembrane neuronal 1.

In the present study we have used genetic association mapping and gene-functional analysis to identify a novel imprinted gene on 2p12, LRRTM1, that we propose is responsible for causing the linkages of this chromosomal region to human handedness and schizophrenia.

Discussion Crow proposed that handedness, brain asymmetry and schizophrenia share an underlying genetic relationship. OMIM is intended for use primarily by physicians and other professionals concerned with genetic disorders, by genetics researchers, and by advanced students in science and medicine.

Q86UE6 Secondary accession number s: There was no significant paternal overtransmission of any other haplotype, nor was there maternal overtransmission of any haplotype.


Our data suggest that a subtype of schizophrenia, linked to misregulation of human LRRTM1, may have its origins in fetal neurodevelopment.

Epigenetic heterogeneity at imprinted loci in normal populations. Highest levels were reached at postnatal day 1 and persisted into adulthood.

Localized morphological brain differences between English-speaking Caucasians and Chinese-speaking Asians: We genotyped the SNPs rs and either rs or rs the latter are equivalent tagging SNPs according to international HapMap data in four family samples of lrrtk1 European descent that included individuals with schizophrenia or poor-outcome schizoaffective disorder.
