ABSTRACT=<sec><title>Background</title><p>Aplasia cutis congenita (ACC), also called congenital cutaneous hypoplasia, is a serious disease in newborns. Children with ACC often die due to wound infections and bleeding. How the incidence of ACC can be reduced is a question that needs to be solved urgently.</p></sec><sec><title>Case report</title><p>We reported a mother who had delivered two children with ACC, both of whom were diagnosed with ACC type VI, skin defects, limb deformities, and congenital heart malformations. One infant died a few days after birth, and another died <italic>in utero</italic> in the second trimester. Genetic testing in both children showed a heterozygous mutation in the <italic>ITGB4</italic> gene [17q25 exon 8, c. 794 dupC, (<italic>p</italic>. Ala266fs) and exon 15, c. 1860G &gt; A]. The mother later successfully gave birth to a healthy baby using Preimplantation Genetic Testing for Monogenic disorders(PGD-M).</p></sec><sec><title>Conclusion</title><p>The PGD-M technique is highly valuable in reducing the incidence of ACC and improving the prognoses of newborns.</p></sec>
