Few mutations in GJB2, GJB6 or GJA1 genes among other populations of African ancestry
As in previous studies in Africans,  African Americans and Caribbean Hispanics with GJB6 mutations,  we did not find either the GJB6-D13S1830 deletion or coding region changes.
From our analysis, there is no evidence that mutations in GJB2, GJB6 or GJA1 are associated with non-syndromic deafness in sub-Saharan African patients.
In search of genetic markers for nonsyndromic deafness in Africa: A study in Cameroonians and black South Africans with the GJB6 and GJA1 candidate genes.
Absence of GJB2 gene mutations, the GJB6 deletion (GJB6-D13S1830) and four common mitochondrial mutations in nonsyndromic genetic hearing loss in a South African population.
Mutations in GJB2, GJB6, and mitochondrial DNA are rare in African American and Caribbean Hispanic individuals with hearing impairment.
