Genes affected

TRIM27 (HGNC:9975): (tripartite motif containing 27) This gene encodes 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. This protein localizes to the nuclear matrix. It interacts with the enhancer of polycomb protein and represses gene transcription. It is also thought to be involved in the differentiation of male germ cells. Fusion of the N-terminus of this protein with the truncated C-terminus of the RET gene product has been shown to result in production of the ret transforming protein. [provided by RefSeq, Jul 2008]

The c.1135G>A (p.D379N) alteration is located in exon 8 (coding exon 8) of the TRIM27 gene. This alteration results from a G to A substitution at nucleotide position 1135, causing the aspartic acid (D) at amino acid position 379 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
