Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 5P and 1B. PM2PP2PP3_ModerateBP6
The NM_001370259.2(MEN1):c.883C>T(p.Arg295Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000031 in 1,613,192 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R295Q) has been classified as Likely benign.

MEN1-related disorder Uncertain:1
The MEN1 c.898C>T variant is predicted to result in the amino acid substitution p.Arg300Trp. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-64574512-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.R295W variant (also known as c.883C>T), located in coding exon 5 of the MEN1 gene, results from a C to T substitution at nucleotide position 883. The arginine at codon 295 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
