Ocular manifestations of the genetic renal tubulopathies.

BACKGROUND: The genetic tubulopathies are rare and heterogenous disorders that are often difficult to identify. This study examined the tubulopathy-causing genes for ocular associations that suggested their genetic basis and, in some cases, the affected gene. METHODS: Sixty-seven genes from the Genomics England renal tubulopathy panel were reviewed for ocular features, and for retinal expression in the Human Protein Atlas and an ocular phenotype in mouse models in the Mouse Genome Informatics database. The genes resulted in disease affecting the proximal tubules (n = 24); the thick ascending limb of the loop of Henle (n = 10); the distal convoluted tubule (n = 15); or the collecting duct (n = 18). RESULTS: Twenty-five of the tubulopathy-associated genes (37%) had ocular features reported in human disease, 49 (73%) were expressed in the retina, although often at low levels, and 16 (24%) of the corresponding mouse models had an ocular phenotype. Ocular abnormalities were more common in genes affected in the proximal tubulopathies (17/24, 71%) than elsewhere (7/43, 16%). They included structural features (coloboma, microphthalmia); refractive errors (myopia, astigmatism); crystal deposition (in oxalosis, cystinosis) and sclerochoroidal calcification (in Bartter, Gitelman syndromes). Retinal atrophy was common in the mitochondrial-associated tubulopathies. Structural abnormalities and crystal deposition were present from childhood, but sclerochoroidal calcification typically occurred after middle age. CONCLUSIONS: Ocular abnormalities are uncommon in the genetic tubulopathies but may be helpful in recognizing the underlying genetic disease. The retinal expression and mouse phenotype data suggest that further ocular associations may become apparent with additional reports. Early identification may be necessary to monitor and treat visual complications.

OBJECTIVES: Family risk factors are crucial to adolescent mental health. Few studies have investigated the complex relationship between family risk factors and adolescent mental health. This study aims to investigate the complex relationship between family cumulative risk (FCR) and adolescent mental health, and to clarify the factors contributing to adolescent mental health problems. METHODS: This study recruited 903 junior high school students and 991 senior high school students in Changsha, Hunan and was conducted through an offline computer-based questionnaire survey using the Middle School Student Mental Health Scale (MSSMHS) and the Family Cumulative Risk Questionnaire (FCRQ) to assess the mental health status and FCR factors, respectively. Statistical analyses were conducted to clarify the demographic factors influencing MSSMHS total and factor scores, and to analyze the relationship between FCRQ and MSSMHS total and factor scores. RESULTS: Females exhibited more mental health problems than males in various MSSMHS factors (all P<0.05); adolescents were prone to different mental health problems at different stages (junior high school first-grade vs. senior high school first-grade); senior high school first-grade students were more likely to experience academic pressure and maladjustment than junior high school first-grade students (P<0.01), and junior high school first-grade students were more likely to exhibit obsessive, paranoia, and hostility symptoms than senior high school first-grade students (all P<0.01); adolescents with low family intimacy and high family conflict reported more symptoms in every dimension of MSSMHS (all P<0.05); adolecents with poor parent-child separation reported higher obsessive-compulsive symptoms, interpersonal sensitivity, anxiety, academic pressure, maladjustment, emotional instability, and unbalanced mind than those with good parent-child separation (all P<0.05). CONCLUSIONS: Female, low family intimacy, high family conflict, and poor parent-child separation are risk factors of adolescent mental health problems. Higher-grade middle school students are prone to exhibit academic pressure and maladjustment, while lower-grade middle school students are prone to exhibit obsessive, paranoia, and hostility symptoms.
