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

May 20, 2024

The c.22G>A (p.V8M) 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 22, causing the valine (V) at amino acid position 8 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
