Genes affected

RLIG1 (HGNC:25322): (RNA 5'-phosphate and 3'-OH ligase 1) Predicted to act upstream of or within hematopoietic progenitor cell differentiation. [provided by Alliance of Genome Resources, Apr 2022]

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.
