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 21, 2022

The c.167G>A (p.R56H) alteration is located in exon 2 (coding exon 2) of the MID2 gene. This alteration results from a G to A substitution at nucleotide position 167, causing the arginine (R) at amino acid position 56 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
