CASO CLINICO: triplicazione del gene SHOX in un paziente con disgenesia gonadica mista e mosaicismo 46,X,i(Y)(p10)[94]/45,X[13]
PRESENTAZIONE DEL CASO, STORIA CLINICA E SINTOMATOLOGIA Descriviamo il caso di un bambino di 2.5 anni con bassa statura, altezza 84cm (-2DS), SPAN 82.5cm, peso 10 kg (-2.5DS). Nato SGA (EG:40.5), con p.c.: 2480 g (-2.44DS), lunghezza: 47cm (-1.64DS), c.c.: 33 cm (-1.84DS).Stadio PH1G1, volume testicolare: 2 ml con genitali esterni normo-conformati. Era stato sottoposto ad amniocentesi, con diagnosi prenatale di disgenesia gonadica mista associata a cariotipo a mosaico 45,X[25]/46,X,i(Y)[18]. IPOTESI DIAGNOSTICHE • deficit accrescitivo in nato SGA • bassa statura da SHOX-D • ritardo della crescita costituzionale o secondario a malassorbimento INDAGINI DI I E II LIVELLO Per la ridotta velocit…
Novel mutations of the ABCA12, KRT1 and ST14 genes in three unrelated newborns showing congenital ichthyosis.
Abstract Background Congenital ichthyosis (CI) is a heterogeneous group of genetic disorders characterized by generalized dry skin, scaling and hyperkeratosis, often associated to erythroderma. They are rare diseases, with overall incidence of 6.7 in 100,000. Clinical manifestations are due to mutations in genes mostly involved in skin barrier formation. Based on clinical presentation, CI is distinguished in non-syndromic and syndromic forms. To date, mutations of more than 50 genes have been associated to different types of CI. Cases presentation We report on three Italian unrelated newborns showing clinical signs compatible with different forms of CI of variable severity, namely Harlequin…
