Genes affected
MEN1 (HGNC:7010): (menin 1) This gene encodes menin, a tumor suppressor associated with a syndrome known as multiple endocrine neoplasia type 1. Menin is a scaffold protein that functions in histone modification and epigenetic gene regulation. It is thought to regulate several pathways and processes by altering chromatin structure through the modification of histones. [provided by RefSeq, May 2019]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.R330H variant (also known as c.989G>A), located in coding exon 6 of the MEN1 gene, results from a G to A substitution at nucleotide position 989. The arginine at codon 330 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
