Genes affected

FAM161A (HGNC:25808): (FAM161 centrosomal protein A) This gene belongs to the FAM161 family. It is expressed mainly in the retina. Mouse studies suggested that this gene is involved in development of retinal progenitors during embryogenesis, and that its activity is restricted to mature photoreceptors after birth. Mutations in this gene cause autosomal recessive retinitis pigmentosa-28. Alternatively spliced transcript variants have been identified.[provided by RefSeq, Jan 2011]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant, c.2124_2126del, results in the deletion of 1 amino acid(s) of the FAM161A protein (p.Glu709del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs558080743, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with FAM161A-related conditions. ClinVar contains an entry for this variant (Variation ID: 553904). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
