PMID:36355422 reported a large consanguineous Pakistani family with eight affected individuals showing bilateral severe-to-profound hearing impairment. A homozygous splice region variant was identified in STX4 (c.232 + 6T>C), which causes exon skipping and a frameshift, that segregated with hearing impairment in this family.
In silico analysis showed that murine Stx4a is highly and widespread expressed in the developing and adult inner ear. Knockdown of stx4 in zebrafish showed an abnormal startle response, morphological and developmental defects, and a disrupted mechanotransduction function in neuromast hair cells.
This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.
