Dear Editor,Persistent Mullerian duct syndrome(PMDS;Online Mendelian Inheritance in Man[OMIM]:#261550)is a rare autosomal recessive inherent difference in sex development in males with Mullerian duct derivatives,including the uterus,fallopian tubes,and upper part of the vagina.'Approximately 88%of PMDS patients were found to have biallelic variants in the anti-Mullerian hormone(AMH;OMIM:*600957)or AMH type 2 receptor(AMHR2;OMIM:*600956)genes,and the rest were referred as idiopathic.I The serum AMH levels are usually very low or undetectable in PMDS patients with AMH gene mutations but normal or elevated in those with AMHR2 gene ***,an adult Chinese patient with PMDS carrying biallelic variants of the AMH gene was reported to have unexpectedly normal serum AMH *** refer to Supplementary Information of Patient and Methods for methodologies.
