Lab One

Identify the origin of In Vitro Fertilization and the 2010 nobel prize winner associated with this technique.

The first pregnancy achieved through IVF occurred in 1973. However, the first successful IVF birth occurred in 1978 (Louise Brown.) Robert Edwards and Patrick Steptoe carried out this successful conception. Robert Edwards later received the 2010 Nobel Prize in Physiology or Medicine for this development.

Identify a recent paper on fertilisation and describe its key findings.

Halliday, J., Oke, K., Breheny, S., Algar, E., & D, J. A. (2004). Beckwith-Wiedemann syndrome and IVF: a case-control study. Am J Hum Genet, 75(3), 526-528.

This article provides evidence suggesting that children conceived through IVF are significantly more likely to develop imprinting disorders such as Beckwith-Wiedemann syndrome and Angelman syndrome (9 times greater.) It is unknown why IVF causes this increase although suggestions include uniparental disomy of the chromosome and unidentified mutations.

Identify 2 congenital anomalies.

Anencephaly: caused by a failure of the rostral end of the neural tube to close resulting in a lack of brain development. Trisomy 21: caused by the presence of additional genetic material on chromosome 21, either in part or full.
