A heterozygous Glutaredoxin and Cysteine-Rich Domain Containing 1 (GRXCR1) variant of uncertain significance (VUS) was also identified, but it was not considered sufficient to account for the hearing loss, as GRXCR1-related hearing impairment is typically autosomal recessive and requires stronger supporting evidence. Here, GRXCR1 is linked to Hearing impairment.
