Table 1 Relationship between degree of severity of autism and both elevated serum S100B protein levels and increased frequency of serum antiribosomal P protein antibodies in autistic children
Protein levels | Patients with mild to moderate autism (n = 30) | Patients with severe autism (n = 34) | P-value (χ2 test) |
|---|---|---|---|
Normal serum S100B protein (n = 41) | 22 (73.3%) | 19 (55.9%) | 0.77 |
Elevated serum S100B protein (n = 23) | 8 (26.7%) | 15 (44.1%) | (0.27) |
Normal serum antiribosomal P protein (n = 38) | 26 (86.7%) | 12 (35.3%) | 17.44 |
Elevated serum antiribosomal P protein (n = 26) | 4 (13.3%) | 22 (64.7%) | (< 0.001) |
