How is Sjogren-Larsson syndrome (SLS) diagnosed?

SLS can be diagnosed by a biochemical blood test that determines if FADH activity is normal. In addition, because mutations in FADH are known to cause SLS, the gene can be sequenced in order to determine if any mutations are present. This also provides the option of genetic and prenatal testing, which can allow parents to make informed decisions about having children.[1][2]
