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]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAdExome4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.178 is higher than 0.05.
