Genes affected

CEP290 (HGNC:29021): (centrosomal protein 290) This gene encodes a protein with 13 putative coiled-coil domains, a region with homology to SMC chromosome segregation ATPases, six KID motifs, three tropomyosin homology domains and an ATP/GTP binding site motif A. The protein is localized to the centrosome and cilia and has sites for N-glycosylation, tyrosine sulfation, phosphorylation, N-myristoylation, and amidation. Mutations in this gene have been associated with Joubert syndrome and nephronophthisis and the presence of antibodies against this protein is associated with several forms of cancer.

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The CEP290 c.6392A>G variant is predicted to result in the amino acid substitution p.Glu2131Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.095% of alleles in individuals of African descent in gnomAD, which may be too common to be an undocumented pathogenic variant. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
