My nephew has just been diagnosed with a chromasone disorder and I was just curious as to how this will affect him in the future? Apparently he has one extra chromosone which is a female one?

Then he probably has XXY syndrome (Klinefelters syndrome). the chromosome is the basic unit of genetic transfer. Usually we have 23 pairs but something went wrong with your nephew and he ended up with an extra female chromosome.
Rather than going into deep info here I have added a link so that you can study up on it.

Humans have 23 pairs of chromosomes 22+ 2 sex chromosomes. A male has an XY pair of sex chromosomes and a female XX.

Chromosomes are made up of genes which direct the body to make things. Amazingly this is all coded using only 4 chemicals which make up the base pairs. (These are the same 4 for all life on earth, plant and animal).

XXY is called Klinefelter Syndrome.

Affected males are almost always sterile, and some degree of language impairment may be present. In adults, possible characteristics vary widely and include little to no signs of affectedness, a lanky, youthful build and facial appearance, or a rounded body type with some degree of gynecomastia (increased breast tissue). Gynecomastia to some extent is present in about a third of individuals affected, a higher percentage than in the XY population. The far end of the spectrum is also associated with an increased risk of breast cancer, pulmonary disease, varicose veins, diabetes mellitus, rheumatoid arthritis, and osteoporosis, risks shared with women.

I'm thinking of a genetic disorder described as 47, xxy. The normal number of human chromosomes (note spelling) is 46. x is the female gender chromosome and y is the male. 47, xxy is also called Kleinefelter syndrome. Run a search for this syndrome and you'll find lots of websites about it. I'm afraid the overall news is not good.

There are several of these disorders. Down's syndrome for example.

Your nephew has Klinefelter syndrome, which is pretty common. Symptoms include:
tall (around six feet)
small testes or hypogonadism
inability to produce sperm
sparse facial and body hair
gynecomastia
