Family History of CFS

Family history implicate a genetic basis for CFS,  Walsh et al., 2001.  Symptom analysis of australian twins with somatic symptoms, Gillespie et al., 2000,  and the occurrence in families of various syndromes,  Hudson et al., 2003. Seing multiple family members with CFS should not surprise paediatricians, crawley.smith07.txt.

 

A genetic background is also implicated from a study on hypermobility, nijs.etal04.txt, nijs.etal04.pdf and nijs.etal06.txt. Genetic connective tissue disorder Ehlers-Danlos syndrome is associated with FM,  Rowe et al., 1999,  and genetic connective disorder hypermobile joints is correlated with juvenile CFS,  Barron et al., 2001.

 

Family findings consistent with the hypothesis that CFS represents a deregulation of the endocrine system, torres-harding.etal05.txt, torres-harding.etal05.pdf.  Unrelated household members have even higher risks of CFS, underhill.ogorman06.txt.

 

Family History of FM

FM family history suggests genetic implication, arnold.etal04.txt.

 

The mode of inheritance in FM is unknown, but it is most probably polygenic, buskila.etal07.txt. There may be a genetic profile specific for chronic pain states, buskila07.txt.

CFS and anxiety are linked in complex manners without a clear pattern,  Roy-Byrne et al., 2002. Immune factors linked to CFS,  Sabath et al., 2002,. Fatigue have a dramatic effect on functioning in twins discordant for fatigue,  Herrell et al., 2002.  Chronic widespread pain affected general health in twins discordant for pain,  Aaron et al., 2002.  

Studies on cognitive processing in twins discordant for CFS pointed toward a shared genetic trait related to information processing, mahurin.etal04.txt,  mahurin.etal.04.txt, mahurin.etal04.pdf. Cold pressor pain sensitivity in twins discordant, ullrich.etal07.txt, ullrich.etal07.pdf.

Sweden also has a twin registry. CFS appears to be a complex trait resulting from both environmental and genetic sources of variation without pronounced differences by gender, sullivan.etal.05.txt, sullivan.etal.05.pdf.

 

Genetic Profiles
