Five-marker SP110 panel for Degenerative Myelopathy Risk Modifier / DMRM in Pembroke Welsh Corgis.
Overview
This genetic panel analyses five SP110 markers on chromosome 25 used together as a Degenerative Myelopathy Risk Modifier, DMRM, in the Pembroke Welsh Corgi. The test is designed to refine degenerative myelopathy assessment, especially when the known SOD1 risk status is also considered.
Degenerative myelopathy, often abbreviated as DM, is a progressive neurological disease of the spinal cord. Dogs may gradually lose strength and coordination in the hind limbs, drag their feet, become unstable and eventually develop more severe paralysis. In Pembroke Welsh Corgis, SOD1 status is important, but not every dog with an SOD1 risk genotype develops the same signs at the same age.
The SP110 markers are not a simple single-gene cause of DM. They add information about a modifier haplotype that can influence the chance of clinical DM and especially the age at which signs begin in Pembroke Welsh Corgis that are already genetically susceptible through SOD1. This makes the panel most useful as an additional layer on top of DM/SOD1 information, not as a stand-alone DM diagnosis.
Each marker test measures one position in the same SP110 region. Together, the five markers provide a more targeted view of the risk-modifier pattern than a single marker alone. A complete result helps show whether the dog carries no, partial or stronger evidence for the SP110 risk haplotype.
Included subanalyses
This analysis includes the following subanalyses:
Allele combinations & result interpretations
Below, for each tested locus, you will find the possible allele combinations that may be reported within this analysis, together with a brief explanation of their genetic meaning. The interpretation of possible interactions between different loci is included in the report, but is not shown here in full because that would lead to too many combinations on this page. The final expression may also depend on other genes and their interaction.
Genotype / allele combination: GG - no risk allele at DMRM marker 1
This dog carries no risk allele at SP110 marker 1. At this marker, no additional SP110 modifier contribution to DM risk is detected beyond the SOD1 context.
Genotype / allele combination: GA - one risk allele at DMRM marker 1
This dog carries one risk allele at SP110 marker 1. If the dog also has an SOD1 risk genotype, this marker strengthens the modifier signal that can contribute to higher DM risk or earlier onset of signs.
Genotype / allele combination: AA - two risk alleles at DMRM marker 1
This dog carries two risk alleles at SP110 marker 1. Combined with an SOD1 risk genotype, this gives a stronger SP110 modifier pattern and is important for breeding selection and risk planning.
Genotype / allele combination: CC - no risk allele at DMRM marker 2
This dog carries no risk allele at SP110 marker 2. At this marker, no additional SP110 modifier contribution to DM risk is detected beyond the SOD1 context.
Genotype / allele combination: CT - one risk allele at DMRM marker 2
This dog carries one risk allele at SP110 marker 2. If the dog also has an SOD1 risk genotype, this marker strengthens the modifier signal that can contribute to higher DM risk or earlier onset of signs.
Genotype / allele combination: TT - two risk alleles at DMRM marker 2
This dog carries two risk alleles at SP110 marker 2. Combined with an SOD1 risk genotype, this gives a stronger SP110 modifier pattern and is important for breeding selection and risk planning.
Genotype / allele combination: AA - no risk allele at DMRM marker 3
This dog carries no risk allele at SP110 marker 3. At this marker, no additional SP110 modifier contribution to DM risk is detected beyond the SOD1 context.
Genotype / allele combination: AG - one risk allele at DMRM marker 3
This dog carries one risk allele at SP110 marker 3. If the dog also has an SOD1 risk genotype, this marker strengthens the modifier signal that can contribute to higher DM risk or earlier onset of signs.
Genotype / allele combination: GG - two risk alleles at DMRM marker 3
This dog carries two risk alleles at SP110 marker 3. Combined with an SOD1 risk genotype, this gives a stronger SP110 modifier pattern and is important for breeding selection and risk planning.
Genotype / allele combination: AA - no risk allele at DMRM marker 4
This dog carries no risk allele at SP110 marker 4. At this marker, no additional SP110 modifier contribution to DM risk is detected beyond the SOD1 context.
Genotype / allele combination: AG - one risk allele at DMRM marker 4
This dog carries one risk allele at SP110 marker 4. If the dog also has an SOD1 risk genotype, this marker strengthens the modifier signal that can contribute to higher DM risk or earlier onset of signs.
Genotype / allele combination: GG - two risk alleles at DMRM marker 4
This dog carries two risk alleles at SP110 marker 4. Combined with an SOD1 risk genotype, this gives a stronger SP110 modifier pattern and is important for breeding selection and risk planning.
Genotype / allele combination: AA - no risk allele at DMRM marker 5
This dog carries no risk allele at SP110 marker 5. At this marker, no additional SP110 modifier contribution to DM risk is detected beyond the SOD1 context.
Genotype / allele combination: AT - one risk allele at DMRM marker 5
This dog carries one risk allele at SP110 marker 5. If the dog also has an SOD1 risk genotype, this marker strengthens the modifier signal that can contribute to higher DM risk or earlier onset of signs.
Genotype / allele combination: TT - two risk alleles at DMRM marker 5
This dog carries two risk alleles at SP110 marker 5. Combined with an SOD1 risk genotype, this gives a stronger SP110 modifier pattern and is important for breeding selection and risk planning.
