The human gene DNAH10 was identified in a meta-analysis of protein-coding genetic variants that influence waist-to-hip ratio, after adjusting for body mass index, which is associated with increased risk of type 2 diabetes and coronary heart disease. The analysis included 476,546 individuals, 88% with European ancestry and 12% with South and East Asian, African, or Hispanic/Latino ancestry. The human DNAH10 gene has not been introduced into flies.
There is one high-scoring ortholog of DNAH10 in flies, Dhc98D, along with several low-scoring orthologs. Multiple RNAi targeting constructs and one P-element insertion lines have been generated for Dhc98D.
Dhc98D knockdown using neuronal and fat body GAL4 drivers causes a significant increase in the levels of triglycerides.

Obesity is an abnormal accumulation of body fat, usually 20% or more over an individual's ideal body weight. Obesity is associated with increased risk of illness, disability, and death. (http://medical-dictionary.thefreedictionary.com/obesity).
The development of obesity is recognized as having both genetic and environmental components (https://www.sciencelearn.org.nz/resources/203-obesity-genetic-or-environmental).
DNAH10 encodes a dynein axonemal heavy chain protein found in cilia and flagella. Mutations in DNAH10 have been reported to co-segregate with abnormally high circulating HDL-cholesterol levels (pubmed:24891332). In Drosophila, Dhc98D is part of the inner dynein arm complex I1/f, and has a testis-specific knockdown phenotype, unlike other dynein heavy chains like Dhc93AB (DNAH11) which have a defective cilia phenotype in chordotonal neurons (Zur Lage et al. 2019, FBrf0241470).
One human gene to one fly gene; Dhc98D is the only high-ranking ortholog. There are multiple low-ranking orthologs in both flies and humans.
Single, high-ranking ortholog of human DNAH10.
