Gene candidates for germline genetic modification
Direct gene candidates
gobs of radiation resistance. prevent binding of thrombospondin to CD47 with a drug, inhibits NO production and somehow this prevents radiation damage and kills cancer cells. antisense CD47 RNA should do the trick permanently.
There are a number of options here, but with germline modification, a muscle-specific knockout of ACVR2B or myostatin are good choices. Also follistatin overexpression in muscle.
In muscle, this allows greatly improved metabolism and endurance (see 'mighty mice'). Synergistic effect with myostatin inhibition is untested, but intriguing.
As the "guardian of the genome", p53 is missing in many cancers, and has been investigated as a gene therapy option for cancer. Introducing a separate copy, or copies of the gene from the wild-type could reduce the incidence of knockout mutations that normally lead to cancer.
"Apolipoprotein A-1 Milano (also ETC-216, now MDCO-216) (ApoA-1 milano) is a naturally occurring mutated variant of the apolipoprotein A1 protein found in human HDL, the lipoprotein particle that carries cholesterol from tissues to the liver and is associated with protection against cardiovascular disease. ApoA1 Milano was first identified by Dr. Cesare Sirtori in Milan, who also demonstrated that its presence significantly reduced cardiovascular disease, even though it caused a reduction in HDL levels and an increase in triglyceride levels."
Humans are unsuited to digesting some types of branching carbohydrates, which then pass through the intestines and feed annoying bacteria. Not a huge priority, but with the increased metabolic demands from the muscle-enhancing therapies, it can't hurt.
Provides resistance to HIV and plague. Increases risk from West Nile virus, but who gives a fuck about that.

LRP5 gene (strong bones)
Those with the LRP5 gene have extra strong bones.
PCSK5 (lower coronary disease)
Those with the PCSK5 gene have 88 percent lower coronary disease. Also, PCSK9 (according to George Church) is also capable of lowering susceptibility to coronary disease.
"More than 50 different mutations in the APP gene can cause early-onset Alzheimer disease, which begins before age 65."
FUT2 (norovirus / stomach flu resistance)
Those with double FUT2 are resistant to stomach flu.
Lactase persistence (lactose tolerance)
Also known as "C/T(-13910)", and located in the MCM6 gene but with influence on the lactase LCT gene, rs4988235 is one of two SNPs that is associated with the primary haplotype associated with hypolactasia, more commonly known as lactose intolerance in European Caucasian populations. [PMID 11788828], [PMID 15114531]
In these populations, the rs4988235(T) allele is both the more common allele and the one associated with lactase persistence; individuals who are rs4988235(C;C) are likely to be lactose intolerant. In populations of sub-Saharan Africans, though, the rs4988235(T) allele is so rare that it's unlikely to be predictive of lactase persistence, and other SNPs are predictive instead. [PMID 15106124, PMID 17159977]

The polymorphisms rs1800497 and rs2283265 (also known as the Taq1a polymorphism) near the dopamine receptor 2 (DRD2) gene are associated with improvements during working memory training. However this polymorphism comes with serious tradeoffs: antisocial, borderline, dissocial, and avoidant personality disorders, addictive and impulsive behaviors such as binge eating, pathological gambling, and drug abuse. (more)
Other genes and polymorphisms associated with working memory improvements are listed on page 5 table 1: SLC6A3 (DAT1) rs27072 rs40184 rs3863145; DRD4 rs11246226 rs936465 rs7124601; PPP1R1B (DARPP32) rs3764352; MAOA rs6609257; ANKK1 rs1800497 (TAQ1A); DRD2 rs2283265; LMX1A rs4657412; BDNF rs6265; COMT rs4680

- DNA variation in the SNAP25 gene confers risk to ADHD and is associated with reduced expression in prefrontal cortex
Theoretical "heterozygote advantages" genes
The principle here is that diseases such as sickle cell or Tay-Sachs, among many others, persist in a population because having one 'good' and one 'bad' copy of the gene offers a significant advantage - in disease resistance, intelligence, etc.
While it would be nice to find a point mutation that would mimic the benefits of heterozygosity, the most straightforward option would be to give someone both variants of the gene, with ~50% expression of each.
Tetracycline response elements, i.e. tet-on and tet-off, can be used for transgenes where constant expression is undesirable. While a number of options for such inducible expression exist, the tet system is the most studied. It is left as an exercise to the reader to determine which genes would be suitable candidates [I will add some when I get around to it].

dental caries vaccine
a genetically modified strain of Streptococcus mutans called BCS3-L1, is incapable of producing lactic acid, which dissolves tooth enamel, and aggressively replaces native flora. In laboratory tests, rats who were given BCS3-L1 were conferred with a lifetime of protection against S. mutans. Dr. Jeffrey D. Hillman suggests that treatment with BCS3-L1 in humans could also provide a lifetime of protection, or, at worst, require occasional re-applications. He figures the treatment would be available in dentists' offices and "will probably cost less than $100.
