Pathogenic variants of CYP17A1 lead to complete or partial loss of enzymatic activity and clinical presentations of varying severity.

Homozygous variants were seen in 48.0% (n = 223) of patients. Common clinical presentations were hypertension (57.0%, n = 256), hypokalemia (45.4% n = 211), primary amenorrhea (38.3%, n = 178), cryptorchidism (15.3%, n = 71), and atypical genitalia (14.2%, n = 66). Frequently occurring variants included p.Y329Kfs (n = 86), p.D487_F489del (n = 44), and p.W406R (n = 39). More severe variants, such as p.Y329Kfs, were associated with hypocortisolism (P &amp;lt; .05), combined hypokalemia and hypertension (P &amp;lt; .01), and disordered sexual development (P &amp;lt; .01).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main conclusion<\/jats:title>\n                    <jats:p>17-OHD is a rare, frequently misdiagnosed disease.
