ABSTRACTIn recent years, numerous genetic variants have been linked with prelingual hearing loss (HL). Variants in the LOXHD1 gene (lipoxygenase homology domain—1) associated with DFNB77 are highly heterogeneous, with different auditory characteristics varying from stable to progressive and mild to profound. To date, 168 DFNB77 cases have been recorded worldwide. Forty‐one hearing‐impaired (HI) probands, who were previously excluded for a set of four common deafness‐causing genes (viz., GJB2, GJB6, SLC26A4, and CDH23) from 33 HI families, were subjected to clinical exome sequencing (CES) involving 285 genes associated with HL. This was followed by a segregation analysis of the available members in the family. We identified two pathogenic LOXHD1 variants in two unrelated inbred families. One is a novel homozygous pathogenic nonsense variant (c.3999C > A; p.C1333X), whereas the other is a likely pathogenic missense variant (c.6046G > T; p.E2046K). In silico tools such as SIFT, PolyPhen‐2, Mutation Taster, CADD, and REVEL scores were used to predict variant pathogenicity. Furthermore, American College of Medical Genetics and Genomics guidelines specific to HL were applied to finally classify a variant as pathogenic or otherwise. The frequency of LOXHD1 variants identified in our study is 4.88% (2/41). This is the first LOXHD1 report associated with non‐syndromic HL in South Indian families.
