Possible or not: XXY XXXY XXYY XXXXY and YO genotypes

Sex chromosome tetrasomy and pentasomy conditions occur in 1:18 000–1:100 000 male births. While often compared with 47,XXY/Klinefelter syndrome because of shared features including tall stature and hypergonadotropic hypogonadism, 48,XXYY, 48,XXXY and 49,XXXXY syndromes are associated with additional physical findings, congenital malformations, medical problems and psychological features. While the spectrum of cognitive abilities extends much higher than originally described, developmental delays, cognitive impairments and behavioural disorders are common and require strong treatment plans. #genotype #GeneticsFieldOfStudy #XXY #XXXY #XXYY #XXXXY #YO #xxyChromosomeDisorder #XXYSyndrome #xyXxyChromosomes #xyySyndrome #xyyLee #xyyMan #KlinefelterSyndrome #klinefeltersSyndrome #klinefelter #klinefelterSyndromeClass12 #TurnerSyndrome #turnersSyndrome #parsonageTurnerSyndrome #chromosomalDisorder #WhatHappensIfAMaleHasXYY #xxxySyndrome #GenderQuotationSubject #HealthIndustry #NikolaysGeneticsLessons #genetics
