Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 5P and 2B. PM2PM5PP2BP4_Moderate
The NM_001370259.2(MEN1):c.1526G>A(p.Gly509Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000689 in 1,450,556 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G509?) has been classified as Pathogenic.

Multiple endocrine neoplasia, type 1 Uncertain:1
Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This sequence change replaces glycine with aspartic acid at codon 509 of the MEN1 protein (p.Gly509Asp). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and aspartic acid. This variant is present in population databases (rs769355346, ExAC 0.002%). This variant has not been reported in the literature in individuals with MEN1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.G509D variant (also known as c.1526G>A), located in coding exon 9 of the MEN1 gene, results from a G to A substitution at nucleotide position 1526. The glycine at codon 509 is replaced by aspartic acid, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
