Genes affected

FAM161B (HGNC:19854): (FAM161 centrosomal protein B) Predicted to be involved in cilium organization. Located in cytoplasmic microtubule. [provided by Alliance of Genome Resources, Apr 2022]

FAM161B links:

COQ6 (HGNC:20233): (coenzyme Q6, monooxygenase) The protein encoded by this gene belongs to the ubiH/COQ6 family. It is an evolutionarily conserved monooxygenase required for the biosynthesis of coenzyme Q10 (or ubiquinone), which is an essential component of the mitochondrial electron transport chain, and one of the most potent lipophilic antioxidants implicated in the protection of cell damage by reactive oxygen species. Knockdown of this gene in mouse and zebrafish results in decreased growth due to increased apoptosis. Mutations in this gene are associated with autosomal recessive coenzyme Q10 deficiency-6 (COQ10D6), which manifests as nephrotic syndrome with sensorineural deafness. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jun 2012]

Ambry Genetics

Feb 14, 2023

The c.223G>A (p.G75S) alteration is located in exon 1 (coding exon 1) of the FAM161B gene. This alteration results from a G to A substitution at nucleotide position 223, causing the glycine (G) at amino acid position 75 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
