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.

USP34-DT (HGNC:55262): (USP34 divergent transcript)

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM1: In a modified_residue Phosphoserine (size 0) in uniprot entity XPO1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.28722987).

The c.3092C>T (p.S1031F) alteration is located in exon 25 (coding exon 24) of the XPO1 gene. This alteration results from a C to T substitution at nucleotide position 3092, causing the serine (S) at amino acid position 1031 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
