Abstract
BACKGROUND The sequence similarity between CYP21A2 gene and its inactive pseudogene CYP21A1P, and copy number variation (CNV) caused by unequal crossover, make it challenging to characterize the CYP21A2 gene through traditional methods. This study aimed to evaluate the clinical utility of the long-read sequencing (LRS) method in carrier screening and genetic diagnosis of congenital adrenal hyperplasia (CAH) by comparing the efficiency of the LRS method with the conventional multiplex ligation-dependent probe amplification (MLPA) plus Sanger sequencing approaches in CYP21A2 analysis. METHODS In a retrospective study, full sequence analysis of the CYP21A2 and CYP21A1P was performed for three pedigrees through long-range locus-specific PCR followed by LRS based on the Pacific Biosciences (PacBio, California, USA) single-molecule real-time (SMRT) platform, and the results were compared with those obtained from next-generation sequencing (NGS)-based whole exome sequencing (WES) and the traditional methods of MLPA plus Sanger sequencing. RESULTS The LRS method successfully identified seven CYP21A2 variants , including three single nucleotide variants (NM_000500.9:c.1451G>C p.(Arg484Pro), c.293-13A/C>G (IVS2-13A/C>G), c.518T>A p.(Ile173Asn)), one 111-bp polynucleotide insertion, one set of 3'URT variants (NM_000500.9:c.*368T>C, c.*390A>G, c.*440C>T, c.*443T>C) and two types of chimeric genes and straightforwardly depicted the inheritance patterns of these variants within families. Moreover, the LRS method enabled us to determine the cis-trans configuration of multiple variants in one assay, without the need to analyze additional family samples. Compared with traditional methods, this LRS method can achieve a precise, comprehensive and intuitive result in the genetic diagnosis of 21-hydroxylase deficiency (21-OHD). CONCLUSION The LRS method is comprehensive in CYP21A2 analysis and intuitive in result presentation, which holds substantial promise in clinical application as a crucial tool for carrier screening and genetic diagnosis of CAH.

Abstract
Diagnosis of nonclassic adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency (21-OHD) may be challenging due to its occult manifestations. To characterize clinical and molecular features of NCAH patients due to 21-hydroxylase deficiency, we retrospectively included 78 NCAH patients. Their phenotype and genotype were presented and compared. The transcription activities of novel CYP21A2 promoter variants were investigated using a dual-reporter luciferase assay system. This cohort included 53 females (68 %) and 25 males (32 %). The median of onset age was 13 years old (female: 13 range from 7 to 38; male: 11 range from 6 to 71). Menstrual cycle disorder was the most common complaint in females (62 %, n = 33) and for males, it was adrenal incidentalomas (52 %, n = 13). A total of 17 (22 %) patients complained of infertility. The most frequently variant was p.Ile173Asn (20 %, n = 31). Importantly, five variants in the promoter region including - 103/- 126 and - 196/- 296 were found in 21 (27 %) patients. Patients with promoter variants showed older onset age and less impaired hormone levels of 17-hydroxyprogesterone, ACTH, progesterone, and androstenedione. Compared with the wild-type promoter, the basic transcription activity of - 103/- 126 and - 196/- 296 promoter variants were reduced by 57% and 25%, respectively. Therefore, females with menstrual cycle disorders or infertility and males with adrenal incidentaloma should be considered of NCAH due to 21-OHD. When genotyping patients with NCAH, the promoter region of the CYP21A2 gene should be also investigated.

Abstract
BACKGROUND P450 oxidoreductase (POR) deficiency (PORD) is characterized by congenital adrenal hyperplasia (CAH) and disorders of sex development (DSD) in both sexes. PORD can also associate with skeletal defects. However, the prevalence of these phenotypes is unknown. AIM To evaluate the prevalence of CAH, DSD, and infertility of patients with POR gene pathogenic variants by a systematic review of the literature. METHODS The literature search was performed through PubMed, MEDLINE, Cochrane, Academic One Files, Google Scholar, and Scopus databases. All studies reporting information on CAH, DSD, testicular adrenal rest tumor (TARTs), and fertility in patients with POR gene pathogenic variants were included. Finally, the prevalence of abnormal phenotypes was calculated. RESULTS Of the 246 articles initially retrieved, only 48 were included for a total of 119 (46 males and 73 females) patients with PORD. We also included the case of a male patient who consulted us for CAH and TARTs but without DSD. This patient, found to be a carrier of combined heterozygous POR mutation, reached fatherhood spontaneously. All the patients found had CAH. The presence of DSD was found in 65.2%, 82.1%, and 82.1% of patients with compound heterozygosity, homozygosity, or monoallelic heterozygous variants, respectively. The prevalence was significantly higher in females than in males. The prevalence of TARTs in patients with PORD is 2.7%. Only 5 women with PORD became pregnant after assisted reproductive techniques and delivered a healthy baby. Except for the recently reported proband, no other studies focused on male infertility in patients with POR gene variants. CONCLUSION This systematic review of the literature reports the prevalence of CAH, DSD, and TARTs in patients with PORD. The unknown prevalence of POR gene pathogenetic variants and the paucity of studies investigating fertility do not allow us to establish whether PORD is associated with infertility. Further studies on both women and men are needed to clarify this relationship.

Abstract
Genetic screening of Congenital Adrenal Hyperplasia (CAH) is known to be challenging due to the complexities in CYP21A2 genotyping and has not been the first-tier diagnostic tool in routine clinical practice. Also, with the advent of massive parallel sequencing technology, there is a need for investigating its utility in screening extended panel of genes implicated in CAH. In this study, we have established and utilized an Allele-Specific Polymerase Chain Reaction (ASPCR) based approach for screening eight common mutations in CYP21A2 gene followed by targeted Next Generation Sequencing (NGS) of CYP21A2, CYP11B1, CYP17A1, POR, and CYP19A1 genes in 72 clinically diagnosed CAH subjects from India. Through these investigations, 88.7% of the subjects with 21 hydroxylase deficiency were positive for eight CYP21A2 mutations with ASPCR. The targeted NGS assay was sensitive to pick up all the mutations identified by ASPCR. Utilizing NGS in subjects negative for ASPCR, five study subjects were homozygous positive for other CYP21A2 variants: one with a novel c.1274G>T, three with c.1451G>C and one with c.143A>G variant. One subject was compound heterozygous for c.955C>T and c.1042G>A variants identified using ASPCR and NGS. One subject suspected for a Simple Virilizing (SV) 21 hydroxylase deficiency was positive for a CYP19A1:c.1142A>T variant. CYP11B1 variants (c.1201-1G>A, c.1200+1del, c.412C>T, c.1024C>T, c.1012dup, c.623G>A) were identified in all six subjects suspected for 11 beta-hydroxylase deficiency. The overall mutation positivity was 97.2%. Our results suggest that ASPCR followed by targeted NGS is a cost-effective and comprehensive strategy for screening common CYP21A2 mutations and the CAH panel of genes in a clinical setting.
