The incidence of nonscrotal fusion (<jats:italic>P<\/jats:italic>\u2009=\u20090.019) and proximal urethral opening (<jats:italic>P<\/jats:italic>\u2009=\u20090.0002) in the ligand-binding domain (LBD) group was higher than that in the non-LBD group. The phallus length in the LBD group was significantly shorter than that in the non-LBD group (<jats:italic>P<\/jats:italic>\u2009=\u20090.009). The external masculinization score (EMS) in the LBD group was significantly lower than that in the non-LBD group (<jats:italic>P<\/jats:italic>\u2009=\u20090.013). The levels of inhibin-B (INHB; <jats:italic>P<\/jats:italic>\u2009=\u20090.0007), basal luteinizing hormone (LH; <jats:italic>P<\/jats:italic>\u2009=\u20090.033), LH peak (<jats:italic>P<\/jats:italic>\u2009=\u20090.002), and testosterone (T) after human chorionic gonadotropin (HCG) stimulation (<jats:italic>P<\/jats:italic>\u2009=\u20090.001) in the LBD group were higher than those in the non-LBD group. There were 53 variants in 64 patients, including 42 reported and 11 novel AR variants, including p.Met247Arg, p.Asp266Glyfs*39, p.Arg362Serfs*140, p.Ala385Val, p.Glu541Asp, p.Pro613Leu, p.Pro695Leu, p.Asn757Asp, c.1616\u2009+\u20091dup, c.1886-1G\u2009&gt;\u2009A and exon 5\u20137 deletion.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The EMS of patients with AIS in the LBD group was significantly lower than that in the non-LBD group. The phallus length was shorter, and the incidences of proximal urethral opening and nonscrotal fusion were higher, suggesting that the phenotypes in the LBD group were more severe. The levels of INHB, basal LH, peak LH, and T after HCG stimulation in the LBD group were higher than those in the non-LBD group, suggesting that androgen resistance in the LBD group was more severe. We identified 53 variants in 64 patients: 42 reported and 11 novel AR variants. These findings provide new and deeper insight into AIS diagnosis and genetic assessment of AIS.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s40618-022-01894-4","type":"journal-article","created":{"date-parts":[[2022,8,16]],"date-time":"2022-08-16T19:02:23Z","timestamp":1660676543000},"page":"151-158","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Clinical characteristics, AR gene variants, and functional domains in 64 patients with androgen insensitivity syndrome"],"prefix":"10.1007","volume":"46","author":[{"given":"Q.","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"X.","family":"Yin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6144-0750","authenticated-orcid":false,"given":"P.","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,8,16]]},"reference":[{"key":"1894_CR1","doi-asserted-by":"publisher","first-page":"87","DOI":"10.1590\/s0004-27302005000100012","volume":"49","author":"K Melo","year":"2005","unstructured":"Melo K, Mendon\u00e7a B, Billerbeck A, Costa E, Latronico A, Arnhold I (2005) Androgen insensitivity syndrome: clinical, hormonal and molecular analysis of 33 cases.
