2.Chinese Medical Association guideline for clinical diagnosis and treatment of lung cancer (2022 edition).
Chinese Journal of Oncology 2022;44(6):457-490
Lung cancer is the most common malignancy with the highest incidence and mortality in China, which poses a major public health problem. To further standardize the prevention and treatment of lung cancer, improve the prognosis of patients, and provide professional evidence-based medical recommendations to medical professionals across China, the Oncology Society of Chinese Medical Association organized experts from departments of pulmonary medicine, oncology, thoracic surgery, radiotherapy, imaging, and pathology, based on indications approved by China Food and Drug Administration, domestically available drugs, recommendations of international guidelines and current clinical practice in China, integrated the latest evidence-based medical evidence of pathology, genetic testing, immune molecular biomarker detection and treatment methods of lung cancer in recent years. After consensus meetings, the Chinese Medical Association guideline for clinical diagnosis and treatment of lung cancer in China was formulated, which provided recommendations to clinicians, and imaging, laboratory, and rehabilitation professionals.

Chinese Journal of Contemporary Pediatrics 2022;24(7):792-796
OBJECTIVES:
To study the characteristics of UGT1A1 gene mutations in Dong neonates in Sanjiang County of Liuzhou and its association with the pathogenesis of hyperbilirubinemia in Dong neonates.
METHODS:
A prospective analysis was performed on 84 neonates who were diagnosed with unexplained hyperbilirubinemia in the Department of Neonatology, Sanjiang County People's Hospital, from January 2021 to January 2022. Sixty healthy neonates born during the same period were enrolled as the control group. Peripheral blood genomic DNA was extracted for both groups, and UGT1A1 exon 1 was amplified by PCR and sequenced.
RESULTS:
In the case group, 33 neonates were found to have G71R missense mutation, with a mutation rate of 39%. The case group had a significantly higher frequency of A allele than the healthy control group (21% vs 10%, P<0.05). The risk of hyperbilirubinemia in Dong neonates carrying G71R missense mutation was 2.588 times as high as that in healthy neonates carrying wild-type UGT1A1 gene (P<0.05). Hardy-Weinberg equilibrium testing showed that the UGT1A1 G71R locus was in genetic equilibrium in both groups (P>0.05).
CONCLUSIONS
UGT1A1 G71R mutation is a high-frequency gene mutation type in Dong neonates in Sanjiang County, and G71R missense mutation is associated with hyperbilirubinemia in Dong neonates.

OBJECTIVE:
To explore the clinical features and genetic basis for a Chinese pedigree diagnosed with congenital glycosylation disease (CGD).
METHODS:
Clinical manifestations of two brothers were analyzed. Whole exome sequencing was carried out for the sib pair. Suspected variants were verified by Sanger sequencing.
RESULTS:
Both the proband and her younger brother were found to carry compound heterozygous variants of the PMM2 gene, which included a known pathogenic mutation of c.395T>C (p.I132T) and a previously unreported c.448-1(delAG) in the 5' end of exon 6 of the gene.
CONCLUSION
The compound heterozygous variants of the PMM2 gene probably underlay the CGD in the sib pair.

Chinese Journal of Medical Genetics 2022;39(1):52-55
OBJECTIVE:
To explore the genetic basis for a Chinese patient with retinitis pigmentosa (RP).
METHODS:
Whole exome sequencing (WES) was carried out to screen potential variant in the proband. Candidate variants were determined by taking consideration of clinical phenotype. Sanger sequencing was used to verify the variant in the proband and his parents.
RESULTS:
The proband was found to harbor compound heterozygous variants of c.8G>A (p.Cys3Tyr) and c.958_959insA (p.Arg320Glnfs*29) in the C2ORF71 gene, which has derived from his father and mother, respectively. Both variants were unreported previously. Based on the ACMG guidelines, they were predicted to be likely pathogenic and pathogenic, respectively.
CONCLUSION
The novel compound heterozygous variants of the C2ORF71 gene probably underlay the pathogenesis of RP in the proband. Above finding has enriched the spectrum of C2ORF71 gene mutations and facilitated genetic counseling for the family.

OBJECTIVE:
To analyze the clinical features and variants of ABCD1 gene in a Chinese pedigree affected with X-linked adrenoleukodystrophy.
METHODS:
Clinical data of the proband were collected and analyzed. Potential variant of the ABCD1 gene were analyzed by PCR and Sanger sequencing of the proband, his parents and 100 unrelated healthy individuals.
RESULTS:
The prominent features of the proband included cerebellar and brainstem lesions, along with increased serum level of very-long chain fatty acids. He was found to harbor a hemizygous c.1509delG (p.L504Sfs*54) variant of the ABCD1 gene, for which his mother was heterozygous. The same variant was not detected in his father and 100 healthy controls.
CONCLUSION
X-linked adrenoleukodystrophy has a variety of clinical manifestations. Discovery of the c.1509delG (p.L504Sfs*54), as a novel pathogenic variant of the ABCD1 gene, has enabled diagnosis and genetic counseling for this pedigree.

Chinese Journal of Medical Genetics 2022;39(2):198-201
OBJECTIVE:
To analyze the clinical phenotype and genetic variant in a Chinese pedigree affected with benign familial neonatal convulsion (BFNC).
METHODS:
Clinical data and peripheral blood samples of the pedigree were obtained with informed consent. Whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing.
RESULTS:
The pedigree comprised 9 individuals, among whom 4 were affected, including 3 males and 1 female. All patients had developed seizures during the neonatal period, which had ceased in 4 to 6 months. One patient had recurrence in between 1 and 2 years old. Genetic testing has identified a novel nonsense c.810G>A (p.W270X) variant in exon 5 of the KCNQ2 gene, which has co-separated with the BFNC phenotype in the pedigree.
CONCLUSION
The patients from this pedigree have conformed to the diagnosis of BFNC with good prognosis, which was in keeping with previously reported cases. The heterozygous c.810G>A (p.W270X) nonsense variant of the KCNQ2 gene probably underlay the pathogenesis of BFNC in this pedigree, which has expanded the mutational spectrum of the disease.

OBJECTIVE:
To study the polymorphism of human platelet antigen (HPA) system 10 among ethnic Han Chinese from Shandong, China so as to supplement the data of platelet donor bank in the region.
METHODS:
Peripheral blood samples of platelet donors from the region were genotyped for HPA-10 alleles by PCR-sequence specific primer (PCR-SSP) and direct sequencing.
RESULTS:
Among 1401 donors, a rare heterozygote carrier of HPA-10w (a+b+) was identified, which gave an allelic frequency of approximately 0.035%.
CONCLUSION
The detection of rare HPA-10bw antigen allele among ethnic Han Chinese from Shandong is useful for the diagnosis and prevention of neonatal alloimmune thrombocytopenia and post-transfusion purpura in the region.

OBJECTIVE:
To determine the carrier rate for 21 inherited metabolic diseases among a Chinese population of childbearing age.
METHODS:
A total of 897 unrelated healthy individuals (including 143 couples) were recruited, and DNA was extracted from their peripheral blood samples. Whole exome sequencing (WES) was carried out to screen potential variants among 54 genes associated with 21 inherited metabolic diseases. Pathogenic and likely pathogenic variants and unreported loss-of-function variants were analyzed.
RESULTS:
One hundred fourty types of pathogenic/likely pathogenic variants (with an overall number of 183) and unreported loss-of-function variants were detected, which yield a frequency of 0.20 per capita. A husband and wife were both found to carry pathogenic variants of the SLC25A13 gene and have given birth to a healthy baby with the aid of preimplantation genetic diagnosis. The detected variants have involved 40 genes, with the most common ones including ATP7B, SLC25A13, PAH, CBS and MMACHC. Based on the Hardy-Weinberg equilibrium, the incidence of the 21 inherited metabolic diseases in the population was approximately 1/1100, with the five diseases with higher incidence including citrullinemia, methylmalonic acidemia, Wilson disease, glycogen storage disease, and phenylketonuria.
CONCLUSION
This study has preliminarily determined the carrier rate and incidence of 21 inherited metabolic diseases among a Chinese population of childbearing age, which has provided valuable information for the design of neonatal screening program for inherited metabolic diseases. Pre-conception carrier screening can provide an important measure for the prevention of transmission of Mendelian disorders in the population.
