METHODS: Ethical Compliance: Written informed consent was obtained from the parents. Here, we report a genetically confirmed Mexican patient with EvCS having two inherited pathogenic variants in trans in EVC2: c.[1195C>T];[2161delC].
RESULTS: This patient allowed a genotypic-phenotypic comparison with another Mexican subject who presented a more attenuated phenotype; furthermore, our patient also presented cleft palate, a rarely reported feature.
CONCLUSIONS: Our case shows the importance of comparing functional hemizygosity between patient\'s phenotypes when they share a variant, and our case also supports the association of alterations in the palate as part of the EvCS phenotype.
方法:道德遵从性:获得父母的书面知情同意书。这里,我们报告了一名经遗传证实的墨西哥EvCS患者,在EVC2中具有两种遗传的反式致病变异:c。[1195C>T];[2161delC]。
结果:该患者允许与另一位表现出更减毒表型的墨西哥受试者进行基因型-表型比较;此外,我们的病人还出现了腭裂,很少报道的特征。
结论:我们的案例显示了比较患者表型之间功能半合子的重要性,我们的病例也支持上颚改变作为EvCS表型的一部分的关联。
