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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.811
BS2
High AC in GnomAdExome4 at 12 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
