Clinical characteristics and molecular diagnosis in 2 cases of P450 oxidoreductase deficiency / 中华内分泌代谢杂志

Objective To analyze clinical characteristics and gene mutation of two patients diagnosed with P450 oxidoreductase deficiency(PORD). Methods Clinical data of 2 patients with PORD was collected from Ruijin hospital. POR gene mutation was analyzed by PCR-Sanger sequencing. A retrospective analysis of literatures concerning PORD was performed. Results Patient 1, female, 16 years old, with 46,XX karyotype, presented with anorectal anomalies, clitoral hypertrophy at birth and irregular menstruation; Patient 2, female, 32 years old, with 46,XX karyotype, showed irregular menstruation and infertility, both without obvious skeletal deformity. Genetic test of POR gene mutation revealed that patient 1 carried a homozygous missense mutation (R457H) and patient 2 carried a heterozygous mutation (R223X/ Y607C). The two mutations (R223X and Y607C) are reported for the first time in China. Conclusion P450 oxidoreductase deficiency which caused by mutations in POR gene has a variety of clinical manifestations, including abnormal steroid hormone synthesis with or without Antley-Bixler syndrome. The affirmative diagnosis should rely on steroid hormone measurement and POR gene analysis.

A study of congenital lipoid adrenal hyperplasia in two pedigrees / 中华内分泌代谢杂志

The clinical features and laboratory data of two patients with congenital lipoid adrenal hyperplasia (CLAH)were collected. The genomic DNA was extracted from the peripheral blood white cells in the two patients and their family members and the STAR gene was screened for mutations by PCR and Sanger sequencing. Patient 1 was a girl aged 2 years and 8 months,and she visited us because of continual cyanosis for more than two years. Physical examination showed no obvious pigmentation or clitoral hypertrophy,and Tanner stage was B1P1. Clinical examination revealed serum ACTH 1 284.1 pg/ml and 17α-hydoxyprogesterone(17-OHP)0.54 ng/ml, with Karyotype 46, XX. Genetic analysis showed compound heterozygous mutations of c.201_202delCT and c.229C>T in the STAR gene. Her father carried heterozygous c.201_202delCT mutation, and her mother showed heterozygous c.229C>T mutation. Patient 2 was a girl aged 22 years and referred to us because of dark skin for more than 21 years. Physical examination revealed generalized hyperpigmentation,with Tanner stage B5P2. Hormone examination showed ACTH>2 000 pg/ml and serum cortisol 0.77μg/dl. Karyotype analysis revealed 46,XX. Genetic analysis found compound heterozygous mutations of c.64+1G>C and c.707_708delinsCTT in the STAR gene,which descended from her father and mother respectively. Of note,c.64+1G>C is a novel splicing mutation of STAR gene.

A case of 21-hydroxylase deficiency in Turner's syndrome and literature review / 中华内分泌代谢杂志

To improve the recognition and treatment of the combination of classical congenital adrenal hyperplasia (CAH) and Turner's syndrome. A case of 21-hydroxylase deficiency (21-OHD) in 45,X[3] / 46,XX [47] was reported,and the related literatures were reviewed. A 29-year-old woman with 45,X[3] / 46,XX[47] was referred with clitorimegaly and primary amenorrhea. Her height was 150 cm with a weight of 56 kg. Physical examination revealed a Tanner stage Ⅵ for both breast development and pubic hair development. She showed a little signs of Turner' s syndrome, such as cubitus valgus. Lab findings: sex hormones are significantly increased, including progesterone, testosterone, dehydroepiandrosterone, 17 hydroxyprogesterone, dihydrotestosterone, and androstendione. Enhanced CT scan showed bilateral adrenal hyperplasia. Gynecological ultrasound showed that the size of the uterus and ovary were near normal and the endometrium was not clear. By gene mutation screening, two mutation sites were found in CYP21A2 gene, such as IVS2-13C/ A→G and p. Ile173Asn( c. 518T→A). Taken together, the patient was diagnosed as a combination of 21-OHD and Turner syndrome. A total of ten patients associated with CAH in Turner's syndrome have been reported so far. The findings showed that routine karyotyping during investigations of patients presenting with ambiguous genitalia or with a diagnosis of CAH may reveal the concomitant presence of Turner's syndrome. We should make a definite diagnosis and give early treatment as soon as possible.

Autoimmune hypophysitis / 中华内分泌代谢杂志

Autoimmune hypophysitis is an inflammation of the pituitary gland resulting from autoimmune response, which can be classified as primary hypophysitis and secondary hypophysitis according to the etiology.The clinical presentation includes hypopituitarism and a pituitary mass.The diagnosis is based on clinical findings and radiology, while the pathology serves as the golden standard.The treatment is aimed at reducing the size of the pituitary mass, replacing the defective hormones and decreasing hyperprolactinemia.This review is about the epidemiology, pathogenesis, diagnosis, and treatment of lymphocytic hypophysitis, hypophysitis secondary to cytotoxic T-4 blockade, and IgG4-related hypophysitis.
