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

DNA sequence analysis of the CEP290 gene demonstrated a sequence change, c.4102G>A, in exon 32 that results in an amino acid change, p.Asp1368Asn. This sequence change has been described in the gnomAD database with a frequency of 0.54% in the African/African American subpopulation (dbSNP rs184143186). The p.Asp1368Asn change affects a poorly conserved amino acid residue located in a domain of the CEP290 protein that is not known to be functional. The p.Asp1368Asn substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change does not appear to have been previously described in individuals with CEP290-related disorders. Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Asp1368Asn change remains unknown at this time. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
