Molecular analysis identified six novel pathogenic variants across the CYP11B1, HSD3B2, StAR, CYP11A1, and CYP11B2 genes, expanding the mutational spectrum.<h4>Conclusion</h4>These results broaden the existing understanding of the mutational landscape underlying rare CAH and reaffirm that comprehensive clinical and genetic evaluation is essential for differentiating these diagnostically challenging subtypes. This evidence concerns the gene CYP11B2 and congenital adrenal hyperplasia.
