Monogenic hearing loss

Gene: TMEM132E

Two publications support the addition of this gene to the panel:

PMID: 25331638 - Li et al 2015 - report two siblings with prelingual, bilateral, severe to profound sensorineural hearing loss in a consanguineous Chinese family. Whole‐exome sequencing revealed a homozygous missense mutation c.1259G>A (rs139895222), p.Arg420Gln, in TMEM132E that cosegregates with deafness in the family. The parents and a brother were heterozygous. The 1259A allele was not found in 500 ethnically matched controls. Immunofluorescence staining of the Organ of Corti showed Tmem132e highly expressed in murine inner hair cells and knockdown of the tmem132e ortholog in zebrafish affected the mechanotransduction of hair cells. Wild‐type human TMEM132E mRNA, but not the mRNA carrying the c.1259G>A mutation rescued the Tmem132e knockdown phenotype.

PMID: 31656313 - Liaqat et al 2019 - a family of Pakistani origin with prelingual profound sensorineural hearing impairment displaying AR mode of inheritance was investigated via exome and Sanger sequencing. Compound heterozygous variants c.382G>T: p.(Ala128Ser) and c.2204C>T: p.(Pro735Leu) in TMEM132E were observed in affected but not in unaffected family members.
