MMP1 Gene Overview
What It Does:
MMP1 (Matrix Metalloproteinase-1), also known as collagenase, is a zinc-dependent enzyme that breaks down interstitial collagens (types I, II, and III). This process is critical for normal tissue remodeling but can also play a role in diseases such as arthritis and cancer metastasis.
Why This Matters:
Excessive MMP1 activity can lead to increased collagen breakdown, potentially contributing to joint degeneration and connective tissue damage.
Understanding the MMP1 Variant
Key Mutation:
- –1607 1G/2G
Impact of the 2G Allele
Impact Allele:
- 2G Allele (Negative)
What It Means for You:
- Increased Collagen Breakdown:
- The 2G allele has significantly greater activity compared to the 1G allele, leading to increased MMP1 transcription and higher levels of collagen degradation.
- Associated Risks:
- Individuals with the 2G/2G genotype have a 2.47 times higher risk of developing temporomandibular joint (TMJ) degeneration compared to 1G/2G or 1G/1G carriers.
Next Steps:
- Monitor for symptoms of joint discomfort or connective tissue issues, such as TMJ pain.
- Discuss targeted interventions, such as dietary modifications or physical therapy, with your genomics specialist or doctor.
