Genes affected

MMP9 (HGNC:7176): (matrix metallopeptidase 9) Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Most MMP's are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The enzyme encoded by this gene degrades type IV and V collagens. Studies in rhesus monkeys suggest that the enzyme is involved in IL-8-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.005083561).

BP6

Variant 20-46011209-G-A is Benign according to our data. Variant chr20-46011209-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 338549.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0111 (1689/152218) while in subpopulation AFR AF = 0.0388 (1613/41520). AF 95% confidence interval is 0.0373. There are 35 homozygotes in GnomAd4. There are 771 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 1689 Unknown,AD gene.
