August 2024 in “American Journal of Medical Genetics Part A” Trichohepatoneurodevelopmental syndrome (THNS) is an ultra-rare disorder characterized by liver dysfunction, hypotonia, developmental delay, coarse hair, and dysmorphic features. This report describes the fifth and sixth cases of THNS from Saudi Arabia, both presenting with these symptoms. Genetic analysis revealed pathogenic variants in the CCDC47 gene: a homozygous variant in Case 1 and two heterozygous variants in Case 2, confirmed to be in trans phase through parental testing. These findings contribute to a stronger gene-disease association and help clarify the clinical phenotype and mutational spectrum of THNS.
