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.
Less than 25% of people who need hearing aids get them. We believe a great portion of the 26.5 million people do not have hearing aids because they are affected by outrageous unyielding costs. Imagine if we can help another one million people get hearing aids because they can afford them!
