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 Benign. Variant got -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.49).
• BP6: Variant 13-36872725-C-A is Benign according to our data. Variant chr13-36872725-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 474935.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-4.02 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 16 AD gene.
