Genes affected
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]

Temtamy syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 01, 2022This variant has not been reported in the literature in individuals affected with C12orf57-related conditions. This variant is present in population databases (rs782311451, gnomAD 0.0009%). This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 43 of the C12orf57 protein (p.Ala43Ser). ClinVar contains an entry for this variant (Variation ID: 581132). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. -
