Objective: To assess the association of ethnicity and birthplace on emotional and psychosexual well-being in women with polycystic ovary syndrome (PCOS)., Design: Cross-sectional study., Setting: Community recruitment via social media campaigns., Population: Women with PCOS completing an online questionnaire in September-October 2020 (UK) and May-June 2021 (India)., Methods: The survey has five components, with a baseline information and sociodemographic section followed by four validated questionnaires: Hospital Anxiety and Depression Scale (HADS); Body Image Concern Inventory (BICI); Beliefs About Obese Persons Scale (BAOP); and Female Sexual Function Index (FSFI)., Main Outcome Measures: We used adjusted linear and logistic regression models, adjusting for age, education, marital status and parity, to evaluate the impact of ethnicity and birthplace on questionnaire scores and outcomes (anxiety and/or depression, HADS ≥ 11; body dysmorphic disorder (BDD), BICI ≥ 72)., Results: A total of 1008 women with PCOS were included. Women of non-white ethnicity (613/1008) reported higher rates of depression (OR 1.96, 95% CI 1.41-2.73) and lower BDD (OR 0.57, 95% CI 0.41-0.79) than white women (395/1008). Women born in India (453/1008) had higher anxiety (OR 1.57, 95% CI 1.00-2.46) and depression (OR 2.20, 95% CI 1.52-3.18) but lower BDD rates (OR 0.42, 95% CI 0.29-0.61) than women born in the UK (437/1008). All sexual domains, excluding desire, scored lower for non-white women and women born in India., Conclusions: Non-white women and women born in India reported higher emotional and sexual dysfunction, whereas white women and women born in the UK reported higher body image concerns and weight stigma. Ethnicity and birthplace need to be considered for tailored, multidisciplinary care., (© 2023 The Authors.

Genetic disorders with predominant central nervous system white matter abnormalities (CNS WMAs), also called leukodystrophies, are heterogeneous entities. We ascertained 117 individuals with CNS WMAs from 104 unrelated families. Targeted genetic testing was carried out in 16 families and 13 of them received a diagnosis. Chromosomal microarray (CMA) was performed for three families and one received a diagnosis. Mendeliome sequencing was used for testing 11 families and all received a diagnosis. Whole exome sequencing (WES) was performed in 80 families and was diagnostic in 52 (65%). Singleton WES was diagnostic for 50/75 (66.67%) families. Overall, genetic diagnoses were obtained in 77 families (74.03%). Twenty-two of 47 distinct disorders observed in this cohort have not been reported in Indian individuals previously. Notably, disorders of nuclear mitochondrial pathology were most frequent (9 disorders in 20 families). Thirty-seven of 75 (49.33%) disease-causing variants are novel. To sum up, the present cohort describes the phenotypic and genotypic spectrum of genetic disorders with CNS WMAs in our population. It demonstrates WES, especially singleton WES, as an efficient tool in the diagnosis of these heterogeneous entities. It also highlights possible founder events and recurrent disease-causing variants in our population and their implications on the testing strategy., (© 2021 John Wiley & Sons A/S.

Osteosclerotic metaphyseal dysplasia (OSMD) is a rare skeletal dysplasia characterized by osteosclerotic metaphyses with osteopenic diaphyses of the long tubular bones. Our previous study identified a homozygous elongation mutation in leucine-rich repeat kinase 1 gene (LRRK1) in a patient with OSMD and showed that Lrrk1 knockout mice exhibited phenotypic similarity with OSMD. Here we report a second LRRK1 mutation in Indian sibs with OSMD. They had homozygous mutation (c.5971_5972insG) that produces an elongated mutant protein (p.A1991Gfs*31) similar to the first case. The sibs had normal stature, normal intelligence and recurrent fractures. The common radiographic feature was asymmetric and variable sclerosis of vertebral end plates, pelvic margin and metaphyses of tubular bones. One of the sibs had facial dysmorphisms, dentine abnormalities and acro-osteolysis. A comparison between the three OSMD cases with LRRK1 mutations with different ages suggested that the sclerotic lesions resolved with age. Our findings further support that LRRK1 would cause a subset of OSMD cases.
