We report that maternal transmission of a GABRB3 signal peptide variant (P11S), previously implicated in childhood absence epilepsy, is associated with autism.
However, allele frequencies of rs20317 and rs4906902 were not significantly associated with 48 rCAE patients in comparison to >500 controls matched for ethnicity and ancestral origin.
GABRB3 mutation, G32R, associated with childhood absence epilepsy alters α1β3γ2L γ-aminobutyric acid type A (GABAA) receptor expression and channel gating.
An exon 2 heterozygous missense mutation (G32R) was present in two CAE-affected persons and two persons affected with EEG-recorded spike and/or sharp wave in a two-generation Honduran family.
Further analysis indicated that no associations were found between GABRB3 SNPs and autism on rs2081648 [OR = 0.84 (95% CI) = 0.41-1.72, I<sup>2</sup> = 89.2%] and rs1426217 [OR = 1.13 (95% CI) = 0.64-2.0, I<sup>2</sup> = 83%].

Four haplotypes were significantly associated with BDI (TA and AG for rs3815762 and rs4868029 in GABRP, GG for rs11636988 and rs8024256 in GABRB3 and GAGG for rs2197414, rs4921195, rs13188991, and rs11956731 in GABRA6, with p values of 0.0038, 0.044, 0.0176, and 0.0267, respectively, on 10,000 permutations).

We carried out a structured case-control analysis of three GABRB3 polymorphisms (rs4477673, rs6576618, and rs981778) in 229 patients with nonsyndromic cleft lip with or without cleft palate (CL±P) and in 314 unaffected controls from Brazil.

The rs4906902 G allele of the GABRB3 gene was overrepresented in mTLE patients with depression; individuals homozygous for the G allele showed reduced GABRB3 mRNA expression.
