Minigene assays confirmed that the c.3346\u20135T&amp;gt;C variant caused aberrant splicing via intron retention and exon skipping, clarifying its pathogenicity. The second pregnancy in 2024 independently verified the pathogenicity of this variant combination and disease recurrence.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      This study represents the first report of identical compound heterozygous\n                      <jats:italic>CEP152<\/jats:italic>\n                      variants causing MCPH\u2013SCKS in two consecutive pregnancies. The independent occurrence in the second pregnancy not only confirms the pathogenicity of this variant combination but also provides clinical evidence for the 25% recurrence risk of autosomal recessive disorders.
