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

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.007968068).
• BP6: Variant 12-88102849-C-T is Benign according to our data. Variant chr12-88102849-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 195989.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=10, Benign=1, Likely_benign=2}. Variant chr12-88102849-C-T is described in Lovd as [Likely_benign].
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
