Mesoderm posterior 2
Mesp2, mesoderm posterior 2
This gene encodes a member of the bHLH family of transcription factors and plays a key role in defining the rostrocaudal patterning of somites via interactions with multiple Notch signaling pathways. This gene is expressed in the anterior presomitic mesoderm and is downregulated immediately after the formation of segmented somites. This gene also plays a role in the formation of epithelial somitic mesoderm and cardiac mesoderm. Mutations in the MESP2 gene cause autosomal recessive spondylocostal dystosis 2 (SCD02).

Autosomal Dominant Spondylocostal Dysostosis is Caused by Mutation in TBX6.
New
Sydney, Australia. In Hum Mol Genet, 17 Feb 2013
Over the past decade the genetic basis of several forms of autosomal recessive SCD cases have been solved, with the identification of four causative genes (DLL3, MESP2, LFNG and HES7).
Brothers with hypospadias, vertebral segmentation defects, and intellectual disability: new syndrome?
New
Lucknow, India. In Am J Med Genet A, Dec 2012
Results of cytogenetic and molecular genetic tests performed, including routine karyotype, MLPA (multiplex ligation-dependent probe amplification) for common microdeletions and subtelomeric copy number variants, microarray-CGH analysis, and sequencing of four Notch signaling pathway genes (DLL3, MESP2, LFNG, and HES7), were all normal.
Tetrasomy 15q25.2→qter identified with SNP microarray in a patient with multiple anomalies including complex cardiovascular malformation.
New
Cincinnati, United States. In Am J Med Genet A, Aug 2012
We propose overexpression of three genes, ADAMTSL3, MESP1, and MESP2 as a potential mechanism for cardiac and vessel malformations associated with tetrasomy 15q.
Mutation analysis of MESP2, HES7 and DUSP6 gene exons in patients with congenital scoliosis.
Nanjing, China. In Stud Health Technol Inform, 2011
MESP2, HES7 and DUSP6 genes have been proved to be involved in the etiopathogenesis of congenital scoliosis (CS) in animal embryo studies, however, whether this association was detected in human CS patients also remains unknown.
Identification of genes for bone mineral density variation by computational disease gene identification strategy.
Wuhan, China. In J Bone Miner Metab, 2011
Prediction of transcription factor binding suggested that the minor allele G of rs10178256 might abolish the binding of MESP1 and MESP2 which play vital roles in bone homeostasis, whereas the minor allele G of rs6214 might create an additional binding site for XBP1, a constitutive regulator of endoplasmic reticulum stress response.
Clinical and radiological distinction between spondylothoracic dysostosis (Lavy-Moseley syndrome) and spondylocostal dysostosis (Jarcho-Levin syndrome).
New York City, United States. In Pediatr Radiol, 2011
In contrast, spondylothoracic dysostosis (STD), or Lavy-Moseley syndrome, results in more severe respiratory compromise, is largely linked to Puerto Rican cohorts and is thought to be associated to the MESP2 gene, also a Notch pathway gene.
The repression of Notch signaling occurs via the destabilization of mastermind-like 1 by Mesp2 and is essential for somitogenesis.
GeneRIF
Mishima, Japan. In Development, 2011
Data demonstrate that Mesp2 is a novel component involved in the suppression of Notch target genes.
Spondylothoracic Dysostosis
Seattle, United States. In Unknown Journal, 2010
Molecular genetic testing for MESP2, the only gene known to be associated with spondylothoracic dysostosis, is available on a clinical basis.
Two novel missense mutations in HAIRY-AND-ENHANCER-OF-SPLIT-7 in a family with spondylocostal dysostosis.
Sydney, Australia. In Eur J Hum Genet, 2010
Four genes causing a subset of autosomal recessive forms of this disease have been identified: DLL3 (SCDO1: MIM 277300), MESP2 (SCDO2: MIM 608681), LFNG (SCDO3: MIM609813) and HES7 (SCDO4).
Autosomal dominant spondylocostal dysostosis in three generations of a Macedonian family: Negative mutation analysis of DLL3, MESP2, HES7, and LFNG.
Скопје, Macedonia. In Am J Med Genet A, 2010
The four known monogenic forms of SCD follow autosomal recessive inheritance, have generalized SDV, a broadly symmetrical thoracic cage, and result from mutations in Notch signaling pathway genes-DLL3, MESP2, LFNG, and HES7.
The oscillation of Notch activation, but not its boundary, is required for somite border formation and rostral-caudal patterning within a somite.
GeneRIF
Mishima, Japan. In Development, 2010
Data propose a novel function of Notch signaling, in which a progressive oscillating wave of Notch activity is translated into the rostral-caudal polarity of a somite by regulating Mesp2 expression in the anterior presomitic mesoderm.
Spondylocostal Dysostosis, Autosomal Recessive
Seattle, United States. In Unknown Journal, 2009
Subtypes are defined by identification of two mutant alleles in any one of the four genes known to be associated with autosomal recessive (AR) SCDO: DLL3, MESP2, LFNG, and HES7.
The role of Notch in patterning the human vertebral column.
Review
Sydney, Australia. In Curr Opin Genet Dev, 2009
More specifically it describes that mutations in genes encoding Notch pathway components (DLL3, MESP2, LFNG and HES7) cause severe congenital vertebral defects in humans.
Functional importance of evolutionally conserved Tbx6 binding sites in the presomitic mesoderm-specific enhancer of Mesp2.
GeneRIF
Tokyo, Japan. In Development, 2008
An Mesp2 enhancer knockout mouse bearing mutations in two crucial Tbx6 binding sites does not express Mesp2 in the presomitic mesoderm.
Mesp2 and Tbx6 cooperatively create periodic patterns coupled with the clock machinery during mouse somitogenesis.
GeneRIF
Mishima, Japan. In Development, 2008
Mesp2 protein leads to the suppression of Tbx6 protein expression post-translationally via rapid degradation mediated by the ubiquitin-proteasome pathway

GeneRIF
United States. In Am J Hum Genet, 2008
findings suggest a founder-effect mutation in the MESP2 gene as a major cause of the classical Puerto Rican form of spondylothoracic dysostosis/Jarcho-Levin syndrome
Defective somitogenesis and abnormal vertebral segmentation in man.
Review
Exeter, United Kingdom. In Adv Exp Med Biol, 2007
Only a minority of abnormal segmentation phenotypes appear to follow Mendelian inheritance but three genes--DLL3, MESP2 and LNFG--have now been identified for spondylocostal dysostosis (SCD), a spinal malformation characterized by extensive hemivertebrae, trunkal shortening and abnormally aligned ribs with points of fusion.

GeneRIF
Sydney, Australia. In Birth Defects Res C Embryo Today, 2007
spondylocostal dysostosis (SCD) is caused by mutation in Delta-like 3 (DLL3), Mesoderm posterior 2 (MESP2), and Lunatic fringe (LFNG); three genes that are components of the Notch signaling pathway.
