INTRODUCTION: The pathogenic variants in DEAH-box RNA helicase DHX37 are one of the major causes of 46,XY gonadal dysgenesis and TRS. To date, only 13 different missense variants have been reported. We report two additional cases with different clinical presentation carrying two novel variants in the DHX37 gene. CASE PRESENTATION AND RESULTS: Case 1 (4.4-year-old boy), presented with significant micropenis and cryptorchidism and was diagnosed as TRS. Case 2 (13.5-year-old girl), had a 46,XY karyotype with female external genitalia and was diagnosed as GD. Two novel DHX37 variants affecting the RecA2 domain, p.G478R and p.L627F, were identified in these cases. Both variants identified in the probands were also present in their unaffected mother. DISCUSSION/CONCLUSION: Our findings broaden the variant spectrum of DHX37 in 46,XY DSD individuals.
