The Vel weak phenotype is due to a heterozygous deletion in the same exon, resulting one functional copy of the SMIM1 gene. If a patient who is Vel negative is transfused with Vel positive red blood cells, they may form anti-Vel alloantibodies.
Hearing aids need to be fitted by someone trained specifically in hearing problems. An audiologist or licensed hearing aid provider can make sure your hearing aids fit and work for your type and degree of hearing loss. You also need to consider cost.
Some aids use just a tubing to deliver the sounds or locate a tiny loudspeaker right in the ear canal. Hearing aids will not correct hearing like glasses correct vision. Donât expect 20/20 hearing but they will help you hear in many situations. Your new hearing aids may require follow up visits for technical tweaks by your hearing professional. Adjusting to hearing aids takes time and perseverance, but it is worth it.
