Shared humanity, awareness of socio-economic privilege, and classism during the pandemic as predictors of supporting equal socio-economic policies.

Curr Psychol 2021 Apr 30:1-13. Epub 2021 Apr 30.

Hacettepe University, Ankara, Turkey.

The coronavirus pandemic has caused unemployment to skyrocket, exposed the longstanding inequalities in health care services and working conditions, and mainly affected the poor in different parts of the world. In the current study, we focus on social identity and social class-related factors that are critical during the pandemic to gain insights into what predicts support for policies favoring economic equality in the post-pandemic period. We argue that to the extent that individuals 1) identify with all humanity during the pandemic, 2) are aware of their socio-economic status-based privilege, 3) do not hold classist attitudes, they would support policies favoring economic equality.

Mutation spectrum of hereditary myopathies in Turkish patients and novel variants.

Ann Hum Genet 2021 May 8. Epub 2021 May 8.

Department of Medical Genetics, University of Health Sciences, Dışkapı Yıldırım Beyazıt Research and Training Hospital, Ankara, Turkey.

Hereditary myopathies are a heterogeneous disorder known to be associated with more than 100 genes. Although hereditary myopathy subgroups can be partially described with traditional methods such as muscle biopsy, next-generation sequencing (NGS) is essential to reveal the disease's underlying genetic etiology and molecular mechanisms.
