We ordered temporal bone CT scan, pure tone audiometry and vocal discrimination, immittanciometry, ABR, head self-rotation, complete blood test, fast glucose, serological tests for syphilis, toxoplasmosis, cytomegalovirus, rubella and measles; autoimmune disease factors (rheumatoid factor, C3, C4, reactive C protein, LE cells, antinucleus factor, ASLO, native anti-DNA, alpha 1 glucoprotein, hemosedimentation rate and IgE dosage). This evidence concerns the gene IGHE and rubella.
