Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP3_Moderate

The NM_015704.3(DESI1):c.55G>C(p.Gly19Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000496 in 1,612,702 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/21 in silico tools predict a damaging outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G19S) has been classified as Uncertain significance.

Genes affected

DESI1 (HGNC:24577): (desumoylating isopeptidase 1) Enables importin-alpha family protein binding activity. Involved in protein export from nucleus and regulation of proteasomal ubiquitin-dependent protein catabolic process. Located in cytosol. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

DESI1 links:

XRCC6 (HGNC:4055): (X-ray repair cross complementing 6) The p70/p80 autoantigen is a nuclear complex consisting of two subunits with molecular masses of approximately 70 and 80 kDa. The complex functions as a single-stranded DNA-dependent ATP-dependent helicase. The complex may be involved in the repair of nonhomologous DNA ends such as that required for double-strand break repair, transposition, and V(D)J recombination. High levels of autoantibodies to p70 and p80 have been found in some patients with systemic lupus erythematosus. [provided by RefSeq, Jul 2008]
