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.
Myth: A milder hearing loss is not bad enough for a hearing aid. Fact: Everyone's hearing loss and listening needs are different. By working with your audiologist, you can determine if a hearing aid is needed and how much it will improve your hearing. Myth: Wearing two hearing aids is not necessary. Fact: We normally hear with two ears. Binaural (two-eared) hearing helps us localize sounds, assists us in noisy settings, and provides natural sound quality. Most people with hearing loss in both ears can understand better with two aids than with one.
