ILDR1 and sensorineural hearing loss disorder: In the present study, we identified a novel mutant allele of ILDR1 (p.P69H) located in the immunoglobulin-like (Ig-like) domain through whole-exome sequencing (WES) that segregates as an autosomal recessive nonsyndromic sensorineural hearing loss (SNHL) allele in a Korean family.
