Genetic Variant MEN1:p.Ala411Thr (chr11-64805153-C-T) – ACMG Classification: Uncertain_significance (5 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 9P and 4B. PM1PM5PP2PP3_StrongBS2

The NM_001370259.2(MEN1):c.1231G>A(p.Ala411Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000496 in 1,613,930 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A411V) has been classified as Likely pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 19 uncertain in NM_001370259.2

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-64805152-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 2998066.

PP2

Missense variant in the MEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 113 curated pathogenic missense variants (we use a threshold of 10). The gene has 20 curated benign missense variants. Trascript score misZ: 4.1921 (above the threshold of 3.09). GenCC associations: The gene is linked to pituitary gigantism, multiple endocrine neoplasia type 1, hereditary pheochromocytoma-paraganglioma, familial isolated hyperparathyroidism.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.952

BS2

High AC in GnomAdExome4 at 6 AD gene.
