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.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.01814516 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7.1, offset of 40, new splice context is: ttgGTatgt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PP5

Variant 12-88086038-C-T is Pathogenic according to our data. Variant chr12-88086038-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 285948.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
