2C or Not 2C? That was the question.

We had our much-anticipated appointment at University of Iowa Hospital & Clinics last week. Our stomachs were in knots as we hoped for "no change." With Usher Syndrome, it's a waiting game where the Retinitis Pigmentosa is concerned. It happens at different ages for different people. Generally, people with Type 2 would have a later development than those with Type 1. However, we were still feeling really nervous.

Audrena was a champ for Dr. D., the Pediatric Ophthalmologist, and her associates. She completed the exam, went through some medical questions, and then looked at the genetics report. That's where things got interesting. She explained it to us, and she said things just were not adding up for her. But she reserved judgement until we had talked to Dr. S. after lunch. Dr. S. is an ENT and is in charge of the OTOScope testing lab. So far, though, Audrena's eyes looked good, although she does have some features that were a little interesting to Dr. D. However, it was nothing to be concerned about.

We went to lunch feeling relieved, but we had more questions and were pretty confused at Dr. D.'s opinion of the genetics report. After we checked back in, we waited for Dr. S. And we waited. And we waited. He walked by once. And then he left. We waited, and Randy walked the halls with Audrena to keep her occupied. Dr. D. came out to get a cup of coffee. She explained that she and Dr. S. had been talking, and things were looking good. But she would wait until he called us back to explain. More questions. By that time, I was seriously puzzled.

Finally, Dr. S. returned, and we were called back. He came in and sat down with his report...the one signed by him...the one we had received from the geneticist we originally saw who gave us the Usher 2C diagnosis. He explained that Audrena has two unknown mutations along the Usher 2C gene. However, when tested against all the different databases, only one gene had the potential to be disease-causing. If we understood correctly, it takes two. Then he moved on to review Audrena's anatomy, or her clinical findings. She has an abnormal vestibular system. Usher Type 2 patients have normal vestibular function. She has abnormal cochleas, also generally not consistent with Usher Syndrome. She has profound hearing loss. Usher Type 2 patients typically do not have profound losses. She met some of her milestones later. Usher Type 2 patients meet their milestones on time. He explained that the genetics and clinical findings just do not match up with Usher.

At that point, Randy asked, "Are you telling us that she does not have Usher Syndrome?" I am a little foggy on what Dr. S. actually said because it was such a shock, but he said something like, with today's knowledge, he can say that Audrena does not have Usher Syndrome. In the future, who knows if they will find a new type of Usher Syndrome, or who knows if they will find some other gene. But right now, today, his report will be amended to clarify that Audrena's hearing loss is a recessive, unknown, non-syndromic hearing loss.

Whoa! That took a bit to sink in. We must have questioned him five different times, five different ways. It was just so hard to have gone through the grieving process and then have someone tell us in an instant that it's all ok. I questioned how so many doctors could have misinterpreted the genetics report. He and Dr. D. didn't really know. They were surprised, too, that no one caught it.

Randy and I did give blood because Dr. S. wanted to do a more complete genetic analysis on the three of us to see what he could find, although he expected it to take a year or more. He also mentioned other patients with the same inner ear structure issues and thought there might be potential for a research study.


Dr. D. left us with, "Isn't it nice to ONLY have to worry about her hearing?" Yes, yes it is. But we still couldn't quite believe it. So after the doctors left, the nurse smiled and said, "Would you like me to tell you again? She does not have Usher Syndrome. I can tell you as many times as you would like to hear it!" We kind of laughed, and then we cried. Thankfully she was quick to find a tissue for me!

We spent the long ride home in disbelief. I called Dr. L.'s nurse to give her the news. She was in the same skeptical state as we were. Is he sure? Is he really, really sure? She said Dr. L. would be calling me the next day because he would want to talk to us about it.

Sure enough, the next day Dr. L. called me on my lunch hour. He said, "Well, this is certainly a surprise!" I agreed and said we were not sure what to believe. In a nutshell, he told me that Dr. S.'s lab is one of the best in the country, and maybe one of the best in the world. If Dr. S. said Audrena does not have Usher Syndrome, then he believes Audrena does not have Usher Syndrome. If Dr. S. said her hearing loss is unknown, then there is no one else who will know what caused it. He is just that good. Actually, Dr. L. called Dr. S. "the man" for this type of genetic testing. If there is one person we have been able trust, through this journey, it's been Dr. L. He has never led us astray. So I ended the phone conversation thinking, "If he believes it, then I guess it's safe for me to allow myself to believe it, too."

However, we have spent so much time trying to convince ourselves things would be ok if Audrena had Usher Syndrome that now we find ourselves still trying to protect her eyes. Dr. D. changed her prescription, and when we ordered new glasses we ordered Transitions lenses. I suppose it's ok be cautious no matter what. It's just going to take awhile to work ourselves back to the idea that our baby girl is not going to go blind after all.

Dr. L. had said to me, "If I had to choose between 'unknown' and Usher Syndrome, I would choose 'unknown.'" I agree. We'll take it!
