Genes affected

TRIM46 (HGNC:19019): (tripartite motif containing 46) This gene encodes a protein of the tripartite motif (TRIM) family. The TRIM motif includes zinc-binding domains, a RING finger region, a B-box motif and a coiled-coil domain. TRIM46 is reported to be involved in the proliferation of multiple types of cancer cells including lung and breast cancer. It has also been shown to control neuronal polarity and axon specification by forming uniform microtubule bundles in the axon. [provided by RefSeq, May 2022]

Collection Method: clinical testing

The c.368C>T (p.P123L) alteration is located in exon 3 (coding exon 3) of the TRIM46 gene. This alteration results from a C to T substitution at nucleotide position 368, causing the proline (P) at amino acid position 123 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
