WES detected Exon 1 deletion mutation of AR gene in the proband and Exon 1 heterozygosity deletion in the mother. This mutation may cause disease according to the ACMG guidelines, but this variation has not been reported in CAIS caused by an AR gene.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study genetically characterized a neonate with CAIS, identifying a novel Exon 1 deletion in the AR gene as the underlying cause.
