NCBI Gene: 10586 ENSG00000181541 UniProt: Q9Y586 OMIM: 604357

MAB21L2 encodes a nuclear protein required for normal embryonic eye development and is similar to C. elegans cell fate-determining genes downstream of TGF-beta signaling. Mutations cause microphthalmia/coloboma and skeletal dysplasia syndrome with both autosomal dominant and autosomal recessive inheritance patterns reported. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.549), reflecting its essential role in early developmental processes affecting ocular and skeletal systems.

OMIM ResearchSummary from RefSeq, OMIM, UniProt

This gene is similar to the C. elegans MAB-21 cell fate-determining gene, a downstream target of transforming growth factor-beta signaling. It is thought that this gene may be involved in neural development. The protein encoded by this gene is primarily nuclear, although some cytoplasmic localization has been observed.
