Clergy Tax Factor 5 - Withholding Taxes. A church can withhold income tax (at the minister requests) , but not Social Security and Medicare tax. Let me repeat that...a church CANNOT withhold FICA from a qualifying minister's compensation. Note: Social security and Medicare taxes are collected under two systems.
Researchers have identified several of the various genes responsible for hereditary deafness or hearing loss, most notably the GJB2 gene mutation. As one of the most common genetic causes of hearing loss, GJB2-related hearing loss is considered a recessive genetic disorder because the mutations only cause deafness in individuals who inherit two copies of the mutated gene, one from each parent. A person with one mutated copy and one normal copy is a carrier but is not deaf.
Block mutations are changes to segments of a chromosome, resulting in large scale changes in the DNA of an organism. Block mutations are commonly caused by transposons, mobile genetic elements that can change positions within the genome and, by doing so, alter the sequence of genes. Cystic fibrosis is an example of a disease which can result from a nonsense mutation (this may not be the only cause though). 2  Frameshift mutations occur when the addition or removal of a base alters the reading frame of the gene.
