{Abstract}: UNASSIGNED: UV-sensitive syndrome and Cockayne syndrome (CS) are rare autosomal recessive and transcription-coupled nucleotide excision repair disorders with different clinical manifestations, although some types are allelic.
UNASSIGNED: We report on a patient who passed away at 15 years old with a progeroid-like appearance, cachexia, hearing loss, and dental anomalies, which led us to the diagnosis of Cockayne-like progeroid syndromes. Our clinical exome sequencing including all the known genes of progeroid syndromes revealed a homozygous stop-gain variant in the UVSSA gene.
UNASSIGNED: Although truncating variants in the UVSSA are known to cause UVsS3, their association with CS has not yet been defined. This case might be the first report of a CS-like phenotype caused by a defective UVSSA.
