Differences of Sex Development
Gene: UGGT1
Genitourinary anomalies such as cryptorchidism reported
--
PMID: 40267907 Dardas et al 2025 report 15 affected individuals from 10 unrelated families with biallelic UGGT1 variants. Affected individuals had GDD and intellectual disability of varying severity.
Other cardinal clinical features included microcephaly, seizures, craniofacial dysmorphism, and behavioral abnormalities (autism, ADHD). More variable features included congenital heart disease, cryptorchism; renal anomalies; hepatomegaly; recurrent infections; and skeletal anomalies (scoliosis and/or vertebral anomalies).
Supportive functional evidence also provided.
