Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM2 PM5 PP2 PP3_Moderate PP5

The NM_003400.4(XPO1):​c.1712A>C​(p.Glu571Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E571K) has been classified as Likely pathogenic.

Genes affected

XPO1 (HGNC:12825): (exportin 1) This cell-cycle-regulated gene encodes a protein that mediates leucine-rich nuclear export signal (NES)-dependent protein transport. The protein specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B, MPAK, and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr2-61492337-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376695.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP2: Missense variant where missense usually causes diseases, XPO1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.852
• PP5: Variant 2-61492336-T-G is Pathogenic according to our data. Variant chr2-61492336-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376697.Status of the report is no_assertion_criteria_provided, 0 stars.
