Variant chr13-20783808-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong

The NM_022459.5(XPO4):c.3370A>G(p.Thr1124Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,614,120 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign 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. T1124M) has been classified as Uncertain significance.

Genes affected

XPO4 (HGNC:17796): (exportin 4) XPO4 belongs to a large family of karyopherins (see MIM 602738) that mediate the transport of proteins and other cargo between the nuclear and cytoplasmic compartments (Lipowsky et al., 2000 [PubMed 10944119]).[supplied by OMIM, Mar 2009]

Ambry Genetics

Sep 17, 2021

The c.3370A>G (p.T1124A) alteration is located in exon 23 (coding exon 23) of the XPO4 gene. This alteration results from a A to G substitution at nucleotide position 3370, causing the threonine (T) at amino acid position 1124 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
