Fig. 3. Pedigrees of Nigerian Yoruba families segregating likely causative variants in genes associated with nonsyndromic hearing loss and Usher syndrome.
a Families with variants in genes associated with nonsyndromic hearing loss. b Families with variants in genes associated with nonsyndromic hearing loss or Usher syndrome. Circles represent females and squares indicate males. Solid symbols represent individuals with bilateral severe-to-profound HL; non-shaded symbols represent unaffected individuals; crossed symbols represent deceased individuals. Individuals studied by exome sequencing are indicated by an asterisk, # indicates individuals whose gDNA was not available. The genotype for the candidate variant(s) are shown above each pedigree. + represents the reference allele; /, variants in trans. Only pedigrees with segregation information are presented.
