Genes affected

MID2 (HGNC:7096): (midline 2) 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 microtubular structures in the cytoplasm. Alternate splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Feb 2009]

Ambry Genetics

Apr 10, 2023

The c.848T>C (p.M283T) alteration is located in exon 4 (coding exon 4) of the MID2 gene. This alteration results from a T to C substitution at nucleotide position 848, causing the methionine (M) at amino acid position 283 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
