2.2.1 GWAS of sarcopenia
Genetic association of four measures of sarcopenia, including ASM, LH,
RH and WP, were retrieved from the IEU[29], which
included 450, 243, 461, 026, 461, 089 and 459, 915 participants,
respectively (Supplement Table S1 ). The independent genetic
variants of WP adjusted for BMI were retrained from the BMI-adjusted
GWAS, including 450, 967 individuals of
European ancestry from the UK
Biobank[30]. The corresponding genetic information
of SNPs about 3 different types of COVID-19 infection was reviewed and
collected in the sarcopenia consortium, respectively.
