Objective: Genetic variants in EFTUD2 were proven to influence variable phenotypic expressivity in mandibulofacial dysostosis Guion-Almeida type (MFDGA) or mandibulofacial dysostosis with microcephaly (MFDM). Yet, the association between the severity of clinical findings with variants within the EFTUD2 gene has not been established. Thus, we aim to elucidate a possible genotype–phenotype correlation in MFDM. Methods: Forty articles comprising 156 patients were evaluated. The genotype–phenotype correlation was analyzed using a chi-square or Fisher's exact test. Results: The proportion of patients with MFDM was higher in Caucasian relative to Asian populations. Although, in general, there was no apparent genotype–phenotype correlation in patients with MFDM, Asians tended to have more severe clinical manifestations than Caucasians. In addition, cardiac abnormality presented in patients with intronic variants located in canonical splice sites was a predisposing factor in affecting MFDM severity. Conclusion: Altogether, this article provides the pathogenic variants observed in EFTUD2 and possible genotype–phenotype relationships in this disease.
