Variant summary

Our verdict is Pathogenic. Variant got 19 ACMG points: 19P and 0B. PS1_Very_Strong PM1 PM2 PM5 PP2 PP3_Strong

The NM_001370259.2(MEN1):c.135G>T(p.Glu45Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E45K) has been classified as 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

Verdict is Pathogenic. Variant got 19 ACMG points.

• PS1: Transcript NM_001370259.2 (MEN1) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar as 403819
• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 11 uncertain in NM_001370259.2
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-64809977-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 428029.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP2: Missense variant where missense usually causes diseases, MEN1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.979
