Invitae RCV000695972 SCV000824513 uncertain significance TWIST1-related craniosynostosis; Saethre-Chotzen syndrome 2018-01-22 criteria provided, single submitter clinical testing 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. This variant has not been reported in the literature in individuals with TWIST1-related disease. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change replaces proline with alanine at codon 24 of the TWIST1 protein (p.Pro24Ala). The proline residue is moderately conserved and there is a small physicochemical difference between proline and alanine.
