Genes affected
CEP68 (HGNC:29076): (centrosomal protein 68) Enables protein domain specific binding activity and protein kinase binding activity. Involved in centriole-centriole cohesion and protein localization to organelle. Located in several cellular components, including centriolar satellite; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
RAB1A (HGNC:9758): (RAB1A, member RAS oncogene family) This gene encodes a member of the Ras superfamily of GTPases. Members of the gene family cycle between inactive GDP-bound and active GTP-bound forms. This small GTPase controls vesicle traffic from the endoplasmic reticulum to the Golgi apparatus. Multiple alternatively spliced transcript variants have been identified for this gene which encode different protein isoforms. [provided by RefSeq, Oct 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.590G>A (p.S197N) alteration is located in exon 3 (coding exon 2) of the CEP68 gene. This alteration results from a G to A substitution at nucleotide position 590, causing the serine (S) at amino acid position 197 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
