Genes affected
BGN (HGNC:1044): (biglycan) This gene encodes a member of the small leucine-rich proteoglycan (SLRP) family of proteins. The encoded preproprotein is proteolytically processed to generate the mature protein, which plays a role in bone growth, muscle development and regeneration, and collagen fibril assembly in multiple tissues. This protein may also regulate inflammation and innate immunity. Additionally, the encoded protein may contribute to atherosclerosis and aortic valve stenosis in human patients. This gene and the related gene decorin are thought to be the result of a gene duplication. [provided by RefSeq, Nov 2015]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.019818902).
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000177 (2/112782) while in subpopulation AMR AF= 0.000185 (2/10797). AF 95% confidence interval is 0.0000325. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 24. This position pass quality control queck.

Submissions by phenotype

Cardiovascular phenotype Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
