PMID: 29036432 - DiStasio et al 2017 - report of severe microcephaly (developing to be below -4.0 SD) and severe intellectual disability in the two siblings with a COPB2 homozygous variant.

The siblings were later investigated for low bone mass in PMID: 34450031 - Marom et al 2021 (in which heterozygous variants in COPB2 in 4 other families with probands with osteoporosis and developmental delay were identified, but no microcephaly reported).
