ABSTRACT
OBJECTIVE@#To explore the genotype-phenotype correlation of Cardio-facio-cutaneous syndrome (CFCS) caused by MAP2K1 gene variants.@*METHODS@#Genomic DNA was extracted from peripheral blood sample from a child patient and his parents. Whole exome sequencing (WES) was carried out for the patient. Suspected variant was verified by Sanger sequencing.@*RESULTS@#The patient was a 1-year-8-month old Chinese male who manifested short stature, psychomotor retardation, relative macrocephaly, distinctive facial features, and congenital heart disease. WES test revealed a heterozygous missense c.389A>G (p.Tyr130Cys) variant in the MAP2K1 gene. Sanger sequencing has confirmed the variant as de novo. According to ACMG/AMP guidelines, the variant was classified as pathogenic.@*CONCLUSION@#Compared with previously reported CFCS cases due to MAP2K1 variants. The patient showed obvious behavioral problems, good appetite and tricuspid regurgitation, which may to be novel features for CFCS.
