Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 7P and 5B. PM1PP2PP3_StrongBP6BS2
The NM_001370259.2(MEN1):c.754G>T(p.Asp252Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000558 in 1,614,050 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. D252N) has been classified as Uncertain significance.

MEN1-related disorder Uncertain:1
The MEN1 c.769G>T variant is predicted to result in the amino acid substitution p.Asp257Tyr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.012% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-64575053-C-A), which may be too common to be an undocumented primary cause of disease. Although we suspect that this variant may be benign, 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.D252Y variant (also known as c.754G>T), located in coding exon 3 of the MEN1 gene, results from a G to T substitution at nucleotide position 754. The aspartic acid at codon 252 is replaced by tyrosine, an amino acid with highly dissimilar 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. -
