Genes affected

TRIM9 (HGNC:16288): (tripartite motif containing 9) The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. The protein localizes to cytoplasmic bodies. Its function has not been identified. Alternate splicing of this gene generates two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.092312515).
• BS2: High AC in GnomAdExome at 5 AD gene.

The c.1414G>A (p.A472T) alteration is located in exon 6 (coding exon 6) of the TRIM9 gene. This alteration results from a G to A substitution at nucleotide position 1414, causing the alanine (A) at amino acid position 472 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
