Single cell genome sequencing approaches have identified somatic copy number variants (CNVs) in human neurons, but small sample sizes (<100 neurons) have limited the power to find recurrent patterns such as CNV hotspots in a single individual. Here, the authors develop an approach to map CNVs in 2097 neurons from a neurotypical individual, finding that >10% neurons contain at least one somatic CNV, and enabling deeper investigation of these events.
