    Congenital Adrenal Hyperplasia with Compound Heterozygous I2 Splice and P453S Mutations

    Acta Endo (Buc) 2022 18(2): 228-231 doi: 10.4183/aeb.2022.228

    Background. Congenital adrenal hyperplasia (CAH) is an autosomal recessive inherited disorder caused by congenital deficiency of enzymes involved in cortisol biosynthesis from cholesterol in the adrenal cortex. In this article, we aimed to present a 29-year-old female patient with I2 splice point mutation detected in one allele and P453S mutation on the other allele of CYP21A2 gene associated with 21-hydroxylase deficiency. Her further investigation revealed that her mother had P453S mutation and her father had I2 splice mutation. Case report. A 29-year-old woman with CAH was admitted to our clinic with the request of pregnancy. Her physical examination revealed a height of 151 cm, weight 59 kg, body mass index 25.8 kg/m2. According to Tanner staging, she had Stage 3 breast development and pubic hair. Her laboratory test results were as follows: Glucose: 79 mg/dL (70-100 mg/dL), Creatinine: 0.6 (0.5-0.95 mg/ dL), Sodium: 138 mEq/L (135-145 mEq/L), Potassium: 4.4 mEq/L (3.5-5.1 mEq/L), Cortisol: 0.05 μg/dL, ACTH: <5.00 pg/mL (5-46 pg/mL), 17-OH progesterone: 7.67 ng/mL (0-3 ng/mL). Chromosome analysis revealed a 46, XX karyotype. CYP21A2 gene mutation analysis was performed for the patient whose clinical history and laboratory results were compatible with congenital adrenal hyperplasia. During the reverse dot blot analysis, I2 splice mutation in one allele and P453S mutation in the other allele were detected. Conclusion. Although the I2 splice mutation detected in our case was mostly associated with a saltwasting form of CAH, it was thought that the other P453S mutation detected may explain the relatively good clinical course in our case.

    Thyroid Hormone Resistance: A Case Report

    Acta Endo (Buc) 2021 17(3): 388-392 doi: 10.4183/aeb.2021.388

    Background. Thyroid hormone resistance (RTH) is defined as a decrease in response to thyroid hormones in the target tissue. Most patients present with nonspecific findings. In this article, we aimed to represent a 22-yearold female patient who presented with palpitation, fatigue, and heat intolerance. She was thought to have thyroid hormone resistance and her genetic examination revealed NM_001128177.1 (THRβ): c.1034G > A (p.Gly345Asp) pathogenic variation in the THRβ gene. Case report. A 22-year-old female patient presented with complaints of fatigue, heat intolerance and palpitations. She was taking Propranolol twice daily at admission. Her family history revealed hypothyroidism in her grandmother. Her physical examination results were as follows: height 160 cm, weight 65 kg, body mass index 25.4kg/m2, body temperature 36.5˚C, respiratory rate 18/min, heart rate 86 beats/min, blood pressure 120/80 mmHg. Her palms were sweaty. The heart sounds were normal, and no heart murmur was auscultated. The laboratory results were TSH: 5.31uU/mL, fT3: 6.83 pg/mL, and fT4: 2.43 ng/dL. THRβ gene mutation analysis was requested for our patient whose clinical history and laboratory results were compatible with thyroid hormone resistance. The pathogenic variation NM_001128177.1(THRβ):c.1034G>A (p.Gly345Asp) was detected after analysis. Conclusion. A diagnosis of RTH requires high clinical suspicion and a genetic mutation analysis should be requested in the case of clinical suspicion. In this way, unnecessary anti-thyroid treatment can be prevented.
