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

Dec 11, 2023

The c.490C>T (p.R164C) alteration is located in exon 2 (coding exon 2) of the MID2 gene. This alteration results from a C to T substitution at nucleotide position 490, causing the arginine (R) at amino acid position 164 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
