Deletions of 22q12.1 overlapping this region have been reported in individuals with variable neurodevelopmental and craniofacial anomalies, including cleft or high-arched palate, micro- and/or retrognathia, hypertelorism, low-set and/or dysplastic ears, hypoplastic corpus callosum, mild-to-moderate developmental delay, and intellectual disability with delayed speech (Breckpot 2016, Bosson 2016, Beck 2015). Haploinsufficiency of MN1 has been proposed as the main cause for the phenotypes of patients with 22q12.1 deletions (Beck 2015), a gene that has recently been associated with CEBALID syndrome (OMIM 618774; also known as MN1 C-terminal truncation syndrome), a complex autosomal dominant disorder with significant clinical overlap (Mak 2020). MN1 disruption has also been associated with autosomal dominant susceptibility to meningioma (OMIM 607174). Further, heterozygous and biallelic loss-of-function variants of CRYBB1 are associated with multiple types of cataracts with or without microcornea (OMIM 611544).

Comment:

The copy number loss of 22q12.1q12.2 involves several protein-coding genes, including MN1 (OMIM 156100) and CRYBB1 (OMIM 600929), and is expected to cause phenotypic and/or developmental abnormalities.
