Genes affected

MEST (HGNC:7028): (mesoderm specific transcript) This gene encodes a member of the alpha/beta hydrolase superfamily. It is imprinted, exhibiting preferential expression from the paternal allele in fetal tissues, and isoform-specific imprinting in lymphocytes. The loss of imprinting of this gene has been linked to certain types of cancer and may be due to promotor switching. The encoded protein may play a role in development. Alternatively spliced transcript variants encoding multiple isoforms have been identified for this gene. Pseudogenes of this gene are located on the short arm of chromosomes 3 and 4, and the long arm of chromosomes 6 and 15. [provided by RefSeq, Dec 2011]

Collection Method: clinical testing

The c.28A>G (p.M10V) alteration is located in exon 2 (coding exon 2) of the MEST gene. This alteration results from a A to G substitution at nucleotide position 28, causing the methionine (M) at amino acid position 10 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
