Among more than 90 different cognitive functions (e.g., musical mind, absolute pitch) and dysfunctions (e.g., agraphia, dyscalculia, dyslexia) related to specific cognitive behavioral and neurological disorders we could only find a few monosymptomatic conditions in the OMIM database (http://www.ncbi.nlm.nih.gov/Omim/) with proven or suggested heredity: perfect musical pitch, syn. absolute pitch...; specific language impairment (SLI)...; specific dyslexia, syn. word-blindness...familial developmental dysphasia...; tune deafness; syn. dysmelodia..; congenital anosmia; syn. odor blindness...; inability to smell musk...; hereditary whispering dysphonia...; indifference to pain, syn. congenital analgesia.... ...
