Genes affected
NUP85 (HGNC:8734): (nucleoporin 85) This gene encodes a protein component of the Nup107-160 subunit of the nuclear pore complex. Nuclear pore complexes are embedded in the nuclear envelope and promote bidirectional transport of macromolecules between the cytoplasm and nucleus. The encoded protein can also bind to the C-terminus of chemokine (C-C motif) receptor 2 (CCR2) and promote chemotaxis of monocytes, thereby participating in the inflammatory response. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

Submissions by phenotype

not provided Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 24, 2024This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 41 of the NUP85 protein (p.Lys41Glu). This variant is present in population databases (rs761849736, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with NUP85-related conditions. ClinVar contains an entry for this variant (Variation ID: 1048877). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The NUP85 p.Lys41Glu variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs761849736) and in control databases in 38 of 277422 chromosomes at a frequency of 0.000137 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 37 of 127734 chromosomes (freq: 0.00029) and Other in 1 of 7140 chromosomes (freq: 0.00014), but was not observed in the African, Latino, Ashkenazi Jewish, East Asian, European (Finnish), or South Asian populations. The p.Lys41 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2024The c.121A>G (p.K41E) alteration is located in exon 2 (coding exon 2) of the NUP85 gene. This alteration results from a A to G substitution at nucleotide position 121, causing the lysine (K) at amino acid position 41 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
