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.
For example, if you listen to a lot of music you can use a music programme. Itâs important that the audiologist discusses lifestyle and what the person does. Itâs not just about the hearing loss, itâs about the impact the hearing loss is having on their life to select the relevant programmes. While there are a lot of different programmes, many people donât want their hearing aids to be that complicated. They just want to put them in their ear and forget about them.
