We understand that you are seeking God's intervention in various areas of your life. Firstly, we notice that Jesus Christ was not mentioned in your requests. It is only through Jesus Christ that we have access to God. There is no other name by which we can be saved. "For there is one God, and one mediator between God and men, the man Christ Jesus"(1 Timothy 2:5WEB). Believe in the Lord Jesus Christ, and you will be saved" (Acts 16:31 WEB).
Now let us address your requests. We will pray for a positive change in the genotypes, but we want to remind you that God's will is always perfect. Sometimes, He allows challenges to draw us closer to Him. It's so that His strength can be demonstrated in our weakness. God loves you and your loved ones and He assigns each person a specific genotype with a purpose. While a turnaround is possible, trust in His will as well. Neither shall we pray for a specific genotype. God does promise to be with us in every step and be our strength in any medical diagnosis. "And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me"(2 Corinthians 12: 9 WEB).
We rejoice with you as you prepare for marriage. We pray that God will bless your union and that it will be a testimony of His love and faithfulness. Be sure you move the highlights of your life into God's will. "Marriage is honorable in all, and the bed undefiled: but whoremongers and adulterers God will judge" (Hebrews 13:4 WE). Since you are currently courting, take care to stay true to biblical principles and begin the marriage with no regrets. "Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying" (Romans 13:13 WEB).
As to your admission request, first make sure your fiancee is a match with a lifelong commitment to you and a Christian believer. Also, in the decision to marry, seek God's will. If you should marry, consider the vows explicitly. Seek God's will for your life outside of your fiancee. Know that God provides us free choice and that there are many decisions to be made in the search for a good marriage including whether you are a matched couple. Let there be no yoke from an unbeliever onto a believer. Seek others in the congregation for a complementing spouse if necessary.
Regarding your business, we pray that God will send the right customers and provide the tools you need to succeed. Remember that God is our provider, and He will supply all our needs according to His riches in glory. This is an important time to depend on God rather than use the situation as a chance to be greedy or to gain through theft."But remember the LORD your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today"(Deuteronomy 8:18 WEB)
We pray for good health for you and your loved ones. May God's healing power be upon you and that you may prosper in all things which includes your health and live to testify of God's goodness." Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth" (3 John 1:2 WEB)
We pray for peace in your family and possibly the same for your parents from misunderstanding. You have a part in keeping the peace in your testimony. Bring your part to the relationship. While Jesus Christ was on the cross, He chose to be a peacemaker and save us from our sins."He that hath knowledge spareth his words: and a man of understanding is of an excellent spirit. Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding" (Proverbs 17:27-28 WEB)
We pray that God will send a helper who will be instrumental in turning things around for your good. Remember that God is always with us, and He is our ultimate helper."I will lift up mine eyes unto the hills, from whence cometh my help. My help cometh from the LORD, which made heaven and earth" (Psalm 121: 1-2)
We pray that God will fill you spiritually and that your prayer life will be enriched. Be willing to get alone with God and He will completely reveal Himself to you with answers and teach you how to pray."...when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly" (Matthew 6:6 WEB)
Finally, we pray that God will uphold your family and your relationship as you seek Him to live an example of His Will. This can be marriage. It can be your salvation. Live and seek God's counsel on each decision."Yea, they shall sing in the ways of the LORD: for great is the glory of the LORD" (Psalms 138:5 WEB)
We pray all these requests in the name of Jesus Christ. It is in the name of Jesus that we pray. Amen
