Objective To identify possible associated genetic variants and characterise the clinical presentation of isolated ectopia lentis (IEL).Methods Forty-eight members with 5 generations of an IEL family were enrolled in this study.Peripheral blood samples of all members were collected, and clinical manifestations were observed through physical examination and routine ophthalmological examination.Whole-exome sequencing (WES) was per-formed for two patients to identify disease-causing variants.The target variants were verified by Sanger sequencing in family members and 200 normal controls.Then, candidate variants were verified using Sanger sequencing in family members and 200 healthy controls.SIFT, PolyPhen and MutationTester were used to predict the protein function.Results A total of 13 IEL patients in this family which inherited in an autosomal dominant pattern.The mean age at disease onset was 51.5 years.The main clinical phenotype of this ICE was characterised by ectopia lentis which anterior inclinated to the anterior chamber.As the anterior chamber became shallow, and the angle of the chamber became narrow, and eventually resulted in the secondary glaucoma.A heterozygous missense variant in the fibrillin gene-1 (FBN1) gene (c.3463G>A) was identified by WES, which was present in all patients but was absent in 200 healthy controls.SIFT, PolyPhen and MutationTester predicted that the variant affected protein function.Conclusion This IEL family is characterized by secondary glaucoma as the first symptom which is caused by ectopia lens with inclination.The c.3463G>A of FBN1 gene may be the pathogenic mutation leading to IEL in this family.

Objective : To identify possible associated genetic variants and characterise the clinical presentation of isolated ectopia lentis (IEL) . Methods : Forty - eight members with 5 generations of an IEL family were enrolled in this study. Peripheral blood samples of all members were collected , and clinical manifestations were observed through physical examination and routine ophthalmological examination. Whole⁃exome sequencing (WES) was performed for two patients to identify disease⁃causing variants. The target variants were verified by Sanger sequencing in family members and 200 normal controls. Then , candidate variants were verified using Sanger sequencing in family members and 200 healthy controls. SIFT , PolyPhen and MutationTester were used to predict the protein function. Results : A total of 13 IEL patients in this family which inherited in an autosomal dominant pattern. The mean age at disease onset was 51. 5 years. The main clinical phenotype of this ICE was characterised by ectopia lentis which anterior inclinated to the anterior chamber. As the anterior chamber became shallow , and the angle of the chamber became narrow , and eventually resulted in the secondary glaucoma. A heterozygous missense variantin the fibrillin gene⁃1 (FBN1) gene (c. 3463G > A) was identified by WES , which was present in all patients but was absent in 200 healthy controls. SIFT , PolyPhen and MutationTester predicted that the variant affected protein function. Conclusion This IEL family is characterized by secondary glaucoma as the first symptom which is caused by ectopia lens with inclination. The c. 3463G > A of FBN1 gene may be the pathogenic mutation leading to IEL in this family.

Objective To analyze the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy,and to explore the adverse effects of sarcopenia on patients with ad-vanced lung cancer undergoing anti-tumor therapy.Methods Patients with advanced lung cancer who received anti-tumor therapy in the Department of Oncology of a tertiary hospital in Chengdu from January to December 2021 were continuously included.The incidence situation of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy was evaluated by using the 12th thoracic spine (T12) skeletal muscle index (SMI) standard.According to the diagnostic criteria of sarcopenia,the patients were divided into the sarcope-nia group and the non-sarcopenia group.Multivariate logistic regression was used to analyze the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy.Results A total of 285 patients were included in this study,of which 123 cases (43.15％) were diagnosed as sarcopenia.Multiva-riate analysis showed that gender (P<0.001),pathological stage (P=0.012),creatinine (P=0.031) and BMI (P<0.001) were the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy.The quality of life score of patients in the sarcopenia group was significantly lower than that in the non-sarcopenia group (P=0.035).Conclusion The incidence of sarcopenia in patients with ad-vanced lung cancer undergoing anti-tumor therapy is high,which is related to many factors and affects the quality of life.
