It does so by circulating blood near the surface of the skin, by exhaling warm, humidified air, and by evaporating sweat. These processes function best when ambient temperature is around 70 degrees Fahrenheit, where we feel most comfortable, and they serve to maintain core body temperature around 98 degrees F.
The most common ones are factor V Leiden (a mutation in the F5 gene at position 1691) and prothrombin G20210A, a mutation in prothrombin (at position 20210 in the 3' untranslated region of the gene). The rare forms of congenital thrombophilia are typically caused by a deficiency of natural anticoagulants.They are classified as type I and are more severe in their propensity to cause thrombosis. The main ones are antithrombin III deficiency, protein C deficiency and protein S deficiency.he most common ones are factor V Leiden (a mutation in the F5 gene at position 1691) and prothrombin G20210A, a mutation in prothrombin (at position 20210 in the 3' untranslated region of the gene).

1 The most common severe congenital anomalies are heart defects, neural tube defects and Down syndrome. 2  Although congenital anomalies may be genetic, infectious, nutritional or environmental in origin, most often it is difficult to identify the exact causes.3  Some congenital anomalies can be prevented.ongenital anomalies are also known as birth defects, congenital disorders or congenital malformations. Congenital anomalies can be defined as structural or functional anomalies (e.g. metabolic disorders) that occur during intrauterine life and can be identified prenatally, at birth or later in life.
