The authors proposed that this heterozygous mutation leads to gain of function in the skull, but to loss of function in the developing gonads and that she might harbor a unique set of modifier genes, which exacerbate this testicular phenotype Analysis of NR5A1 in this cohort identified heterozygous changes in seven individuals; all of them were located within the hinge region of the NR5A1 protein.
Cognitive mechanisms underlying disorganization of thought in a genetic syndrome 47,XXY Schizophrenia Research.
Sometimes, random statistical distribution of inactivation in the relatively small number of cells present at the time of inactivation results in a particular descendant tissue having a preponderance of active maternal or paternal X chromosomes skewed inactivation.

What it is said versus how it is said: comprehension of affective prosody in men with Klinefelter 47,XXY syndrome. Brothman A. Dunger, D. A two-hit model has been proposed by Bose et al.
Genetic female patients may also be affected and present normal development of internal and external genitalia at birth and hypergonadotropic hypogonadism and amenorrhea at post pubertal age; enlarged ovaries at adult age and infarction from twisting can occur The second report of NR5A1 defects in humans was described by Biason-Lauber and Schoenle, in a 14 month-old 46,XX girl who had presented primary adrenal insufficiency and seizures Next, we wanted to further explore other variables that may relate to SRS results, including age, verbal and nonverbal cognitive abilities, previous clinical diagnosis of ASD, timing of SCA diagnosis prenatal versus postnatal , and SES.
The CYP17A1 gene, which encodes the enzymes hydroxylase and lyase, is a member of a gene family within the P supergene family and is mapped at 10q The effect of estrogen use during gestation in the etiology of 46,XY DSD has not been confirmed to date Acta Paediatr.
