[ 9 ] Each individual has 2 SMN genes, SMN1 and SMN2 . (medscape.com)
However, all patients with spinal muscular atrophy retain at least 1 copy of SMN2 , which generates only 10% of the amount of full-length SMN protein versus SMN1 . (medscape.com)
Spinal muscular atrophy (SMA) is a genetic disease caused by mutation or deletion of the survival of motor neuron 1 (SMN1) gene. (broadinstitute.org)
Spinal muscular atrophy type 1 (SMA1) is the most common genetic cause of death in infants resulting from bi-allelic mutations of the survival motor neuron gene (SMN1, telomeric), located on chromosome 5q13.2. (asgct.org)
The underlying pathology of SMA is caused by insufficient production of the SMN (survival of motor neuron) protein, essential for the survival of motor neurons, and is encoded by two genes, SMN1 and SMN2. (businesswire.com)
Most kinds of SMA are caused by a problem with a gene that makes this protein, called the SMN1 gene. (kidshealth.org)
SMA is caused by a lack of a functional survival motor neuron 1 also known as SMN1 gene. (reachmd.com)
The SMN1 gene provides instructions for making the survival motor neuron (SMN) protein. (medlineplus.gov)
A small amount of SMN protein is produced from a gene similar to SMN1 called SMN2 . (medlineplus.gov)
In about 5 percent of people with this disorder, one copy of the SMN1 gene is missing a section, and the other copy has a different kind of mutation that disrupts the production or function of the SMN protein. (medlineplus.gov)
The small amount of SMN protein produced by the SMN2 genes can help make up for the protein deficiency caused by SMN1 gene mutations. (medlineplus.gov)
SMA is a deletion of the Survival Motor Neuron 1 (SMN1) gene. (looktothestars.org)

SMN1 helps the body make an important protein that keeps the nerves that control muscle movement healthy. (medlineplus.gov)
Type 1 to 4 are caused by a deficiency in the SMN protein when the mutation is present in both copies of the SMN1 gene on both the maternal and paternal chromosome 5. (chetindia.org)
The deficiency in the SMN1 gene can be partially made up the neighboring SMN2 genes which also produces some functional protein. (chetindia.org)
For these nerve cells to be healthy, our Survival Motor Neuron 1 genes (SMN1 genes) must produce enough Survival Motor Neuron (SMN) protein. (musculardystrophyuk.org)
People with 5q SMA have two faulty copies of the SMN1 gene, which means they are unable to produce enough SMN protein to have healthy lower motor neurons. (musculardystrophyuk.org)
However, most of the SMN protein produced by SMN2 lacks a key building block that is usually produced by SMN1. (musculardystrophyuk.org)
This means that while SMN2 can make some functional SMN protein, it cannot fully make up for the faulty SMN1 gene in people with SMA. (musculardystrophyuk.org)

Mouse models of human disease like nmd provide unique tools for both gene discovery and analysis of underlying disease mechanisms. (sciencedaily.com)
In another significant finding, the researchers report that severity of the nmd's disease traits is suppressed by a modifier gene mapped to a locus (Mnm) on mouse Chromosome 13. (sciencedaily.com)
The Neuron paper reports that the defective gene (designated Smbp2) in the neuromuscular disease mice encodes a DNA-binding protein (SMBP2, or immunoglobulin S-mu binding protein-2) on chromosome 19. (sciencedaily.com)

(sciencedaily.com)

Diseases of neuronal cell disability have few things in common and are a disorder in biochemical processes in neurons: problems with neural conduction, oxidative stress, activation of microglia [MG] cells (microglia are the local macrophages in the brain), and poor function of transferring vital proteins in the brain and cells of the central nervous system [CNS].

However, the role of microglia in TDP-43-mediated motor neuron degeneration remains poorly understood. (nature.com)
In this study, we show that depletion of TDP-43 in microglia, but not in astrocytes, strikingly upregulates cyclooxygenase-2 (COX-2) expression and prostaglandin E2 (PGE2) production through the activation of MAPK/ERK signaling and initiates neurotoxicity. (nature.com)
Moreover, we find that administration of celecoxib, a specific COX-2 inhibitor, greatly diminishes the neurotoxicity triggered by TDP-43-depleted microglia. (nature.com)
Taken together, our results reveal a previously unrecognized non-cell-autonomous mechanism in TDP-43-mediated neurodegeneration, identifying COX-2-PGE2 as the molecular events of microglia- but not astrocyte-initiated neurotoxicity and identifying celecoxib as a novel potential therapy for TDP-43-linked ALS and possibly other types of ALS.
