Description

The c.1350G>C variant (also known as p.Q450H), located in coding exon 8 of the MEN1 gene, results from a G to C substitution at nucleotide position 1350. The amino acid change results in glutamine to histidine at codon 450, an amino acid with highly similar properties. However, this change occurs in the last base pair of coding exon 8, which makes it likely to have some effect on normal mRNA splicing. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and will result in the creation or strengthening of a novel splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). Based on the majority of available evidence to date, this variant is likely to be pathogenic.
