C12ORF57
Chr 12ARchromosome 12 open reading frame 57
Also known as: C10, GRCC10
This protein is required for corpus callosum development in the brain and is ubiquitously expressed across human tissues. Mutations cause Temtamy syndrome, which is inherited in an autosomal recessive pattern. The gene shows low constraint against loss-of-function variants (pLI ~0, LOEUF 1.86), consistent with its recessive inheritance pattern.
