Functional analysis of germline <em>VANGL2</em> variants using rescue assays of <em>vangl2</em> knockout zebrafish
\ua9 The Author(s) 2023. Published by Oxford University Press. Developmental studies have shown that the evolutionarily conserved Wnt Planar Cell Polarity (PCP) pathway is essential for the development of a diverse range of tissues and organs including the brain, spinal cord, heart and sensory organs, as well as establishment of the left-right body axis. Germline mutations in the highly conserved PCP gene VANGL2 in humans have only been associated with central nervous system malformations, and functional testing to understand variant impact has not been performed. Here we report three new families with missense variants in VANGL2 associated with heterotaxy and congenital heart disease p.(Arg169His), non-syndromic hearing loss p.(Glu465Ala) and congenital heart disease with brain defects p.(Arg135Trp). To test the in vivo impact of these and previously described variants, we have established clinically-relevant assays using mRNA rescue of the vangl2 mutant zebrafish. We show that all variants disrupt Vangl2 function, although to different extents and depending on the developmental process. We also begin to identify that different VANGL2 missense variants may be haploinsufficient and discuss evidence in support of pathogenicity. Together, this study demonstrates that zebrafish present a suitable pipeline to investigate variants of unknown significance and suggests new avenues for investigation of the different developmental contexts of VANGL2 function that are clinically meaningful

Discrimination, social capital, and financial constraints: the case of Viet Nam
This paper examines the relationship among gender, social capital, and access to finance of micro, small,and medium enterprises in the manufacturing sector in Viet Nam. Our dataset is from the 2011, 2013, and2015 results of the Micro, Small, and Medium Enterprise Survey in Viet Nam. Using the Heckman technique to control for sample selection bias, the estimates do not provide evidence for discriminationagainst female-owned enterprises in the formal lending market. Specifically, female entrepreneurs havea higher probability of getting a loan and they pay lower interest rates in comparison with male entrepreneurs. No discrimination in formal credit markets may arise from the preference for informal loansover formal loans as entrepreneurs tend to borrow informal loans before applying for formal ones.Further analysis shows that social capital could facilitate loan applications: firms that have a closer relationship with government officials and other business people can get loans of longer duration
Exploring intersectionality issues in entrepreneurial finance: Policy responses and future research directions
Main Message
Entrepreneurial finance scholars (and policy-makers) need to adopt an intersectional approach to their analysis (and policy-making) and pay more attention to the interplay between the owner-manager characteristics of ethnicity/race, gender, and social class.

Exploring intersectionality issues in entrepreneurial finance
Key points
Since most literature on entrepreneurial finance treats ethnicity/race, gender, and class separately, an intersectional approach to analysis is complex, whether social (race, gender, social class) or situational characteristics (entrepreneur versus migrant/social or health care worker).
Women, ethnic minorities, and working-class people are disadvantaged when seeking finance.
We integrate the literature and proposes intersectionality as a framework for policy-makers, since the interplay between these characteristics can be addressed to develop innovative methods of finance
Gender gaps and reentry into entrepreneurial ecosystems after business failure
Despite the significant role played by serial entrepreneurs in the entrepreneurial process, we know little about group differences in reentry decisions after business failure. Using an ecosystems framework and stigma theory, we investigate the variance in gender gaps related to the reentry decisions of 8,171 entrepreneurs from 35 countries who experienced business failures. We find evidence of persisting gender gaps that vary across ecosystem framework conditions of public stigma of business failure and public fear of business failure. Our findings shed new light on ecosystem inefficiencies that arise from multiple interactions between entrepreneurs and institutions
