124:(URA). The mutational spectrum of CFTR in the first group differs from that observed in classic cystic fibrosis, with milder missense or splice variants present on at least one chromosome. The genetic basis of the second group is not well understood. In the subset of males with both CBAVD and URA, the CFTR mutation has been shown to occur at a rate only slightly higher than the overall population. It has been suggested that another gene may be responsible for this condition. 104:

The misdiagnosis ratio of CUAVD was low when scrotal content was otherwise normal (1:48), but higher if anomalies were present (3:12).

Vas deferens are less commonly palpated during routine a physical examination, hence the absence may go unnoticed. Also, injury to Vas deferens common in surgery. Vas deferens may be absent on one or both sides, and in whole or in part. When only a part of Vas deferens is absent, it may fail to

In one of the largest such studies, a study of 23,013 individuals seeking for vasectomy, 159 were suspected to be having UAVD. Among 159 men identified as potentially having CUAVD, 47 had only one testicle, 26 had bilateral vasa, and four were misdiagnosed (post-vasectomy semen analysis showing
