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]

Submissions by phenotype

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 26, 2023For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 438167). This premature translational stop signal has been observed in individual(s) with FAM161A-related conditions (PMID: 28041643, 32581362). This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Asp261Valfs*39) in the FAM161A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FAM161A are known to be pathogenic (PMID: 20705278, 20705279, 24651477). -
