Genes affected

SMAD9 (HGNC:6774): (SMAD family member 9) The protein encoded by this gene is a member of the SMAD family, which transduces signals from TGF-beta family members. The encoded protein is activated by bone morphogenetic proteins and interacts with SMAD4. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00584 (518/88644) while in subpopulation EAS AF= 0.0164 (45/2744). AF 95% confidence interval is 0.0131. There are 2 homozygotes in gnomad4. There are 248 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High AC in GnomAd4 at 518 AD gene.
