Genes affected

CEP104 (HGNC:24866): (centrosomal protein 104) This gene encodes a centrosomal protein required for ciliogenesis and for ciliary tip structural integrity. The mammalian protein contains three amino-terminal hydrophobic domains, two glycosylation sites, four cysteine-rich motifs, and two regions with homology to the glutamate receptor ionotropic, NMDA 1 protein. During ciliogenesis, the encoded protein translocates from the distal tips of the centrioles to the tip of the elongating cilium. Knockdown of the protein in human retinal pigment cells results in severe defects in ciliogenesis with structural deformities at the ciliary tips. Allelic variants of this gene are associated with the autosomal-recessive disorder Joubert syndrome, which is characterized by a distinctive mid-hindbrain and cerebellar malformation, oculomotor apraxia, irregular breathing, developmental delay, and ataxia.

Computational evidence support a benign effect (BayesDel_noAF=-0.58).

BP6

Variant 1-3836504-T-A is Benign according to our data. Variant chr1-3836504-T-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 475456.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.004 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00314 (408/130098) while in subpopulation NFE AF = 0.0049 (306/62424). AF 95% confidence interval is 0.00445. There are 2 homozygotes in GnomAd4. There are 189 alleles in the male GnomAd4 subpopulation. Median coverage is 23. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR gene
