Summaries for N Syndrome

About this section


MalaCards based summary: N Syndrome, also known as NSX, is related to netherton syndrome and xeroderma pigmentosum, and has symptoms including cryptorchidism, sensorineural hearing impairment and megalocornea. An important gene associated with N Syndrome is HPRT1 (hypoxanthine phosphoribosyltransferase 1), and among its related pathways are Purine metabolism and Nucleotide Metabolism. The compounds pyrophosphate and dgtp have been mentioned in the context of this disorder. Affiliated tissues include t cells, testes and heart.
