Genes affected
IKZF5 (HGNC:14283): (IKAROS family zinc finger 5) Members of the Ikaros (ZNFN1A1; MIM 603023) family of transcription factors, which includes Pegasus, are expressed in lymphocytes and are implicated in the control of lymphoid development.[supplied by OMIM, Jul 2002]
PSTK (HGNC:28578): (phosphoseryl-tRNA kinase) Predicted to enable kinase activity and tRNA binding activity. Predicted to be involved in phosphorylation; selenocysteinyl-tRNA(Sec) biosynthetic process; and translation. Predicted to act upstream of or within selenocysteine incorporation.

IKZF5-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesAug 09, 2023The IKZF5 c.254G>A variant is predicted to result in the amino acid substitution p.Arg85Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0056% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-124755572-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
