Genes affected
TGFBR1 (HGNC:11772): (transforming growth factor beta receptor 1) The protein encoded by this gene forms a heteromeric complex with type II TGF-beta receptors when bound to TGF-beta, transducing the TGF-beta signal from the cell surface to the cytoplasm. The encoded protein is a serine/threonine protein kinase. Mutations in this gene have been associated with Loeys-Dietz aortic aneurysm syndrome (LDAS). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.15085885).
BP6
Variant 9-99105251-G-A is Benign according to our data. Variant chr9-99105251-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 477556.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000498 (72/144538) while in subpopulation AFR AF = 0.00174 (70/40260). AF 95% confidence interval is 0.00141. There are 0 homozygotes in GnomAd4. There are 32 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 72 AD gene.
