The deafness family had compound heterozygous mutations in the Chr13:GJB2 gene (NM_004004.5; c.235delC [p.Leu79Cysfs] and c.299_300delAT [p.His100Argfs]); the details regarding cTB isolation (CFC178) and STR identification in this family are described in a previous study (Chang et al, 2021). Here, GJB2 is linked to deafness.
