Genes affected
RNU7-1 (HGNC:34033): (RNA, U7 small nuclear 1) Implicated in Aicardi-Goutieres syndrome. [provided by Alliance of Genome Resources, Apr 2022]
C12orf57 (HGNC:29521): (chromosome 12 open reading frame 57) This gene is ubiquitously expressed in human tissues. It is required for development of the human corpus callosum. Mutations in this gene are associated with Temtamy syndrome (TEMTYS). Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]
