Discussion: Within North America, it was reported that one of the top mutations, 27964C>T-(S24L) in the ORF8 protein, has an unusually strong gender dependence.
Analysis of SARS-CoV-2 mutations in the United States suggests presence of four substrains and novel variants.
Result: Notably, after analyzing 28,726 complete genome sequences, none of them have mutations 28144T>C-(L84S) and 27964C>T-(S24L) happened simultaneously.
Result: Similar to 27964C>T-(S24L), although 17858A>G-(Y541C), 17747C>T-(P504L) are in the final list in Table 1, more than 87% of them were detected in the United States.
Result: The co-mutations of the second groups have eight unique single mutations: 1059C>T-(T85I), 14408C>T-(P323L), 23403A>G
Genomic Epidemiology of SARS-CoV-2 Infection During the Initial Pandemic Wave and Association With Disease Severity.
Result: Several variants were associated with lower hospitalization rate, including 12809C>T (L4182F ORF1ab, 3 of 91 hospitalizations [3.3%] vs 22 of 211 hospitalizations [10.4%]; chi21 = 4.215; P = .04) and 27964C>T (S24L ORF8, 0 of 91 hospitalizations [0%] vs 13 of 211 hospitalizations [6.2%]; chi21 = 5.878; P = .01).

Result: H1-3-3 had previous 5 specific sites and 8 new missense mutation sites (C1059T, C10319T, A18424G, C21304T, G25907T, C27964T, C28472T, and C28869T) (Table 5, Table 6), which increased gradually between December 01, 2020 and February 02, 2021 in the USA.

Discussion: Some mutations (for example, C27964T in ORF8) have been found to have gender dependence with a presumed ratio of 2:1.

Discussion: This finding contradicts with the results of a study conducted in the United States of America, that found the 27964C > T-(S24L) mutation to be more prevalent in females than in males.
