PMID:35727972 reported 13 patients from four unrelated families with non-syndromic sensorineural hearing loss. Four of these patients had prelingual onset of severe to profound, progressive bilateral hearing loss. The other nine patients had congenital onset of severe to profound bilateral hearing loss, which was not progressive on one patient, while data was not available for the other.
Three different homozygous variants (c.144G > A/ p.Trp48Ter, c.412_419delCGGTTTTG/ p.Arg138Valfs*10 and c.393G > T/ p.Lys131Asn) were identified in MINAR2/ KIAA1024L gene in these patients.
There is some functional evidence available for the p.Lys131Asn variant. In addition, mice with loss of function of the Minar2 protein present with rapidly progressive sensorineural hearing loss.
This gene has also been associated with relevant phenotype in OMIM (MIM #620238).
