Mutations in this gene cause autosomal-recessive intellectual disability. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 11. [lettersforcecilia.com]
Of these, VCX3A is linked with intellectual disability. Tests on blood samples from his parents revealed that the deletion was inherited from his mother, although she had no symptoms of either disease. [edmcasereports.com]

Urogenital
- Cryptorchidism
Cryptorchidism is associated with an increased risk of testicular cancers. This risk nearly doubles when cryptorchidism is bilateral. Orchiopexy will reduce, but not eliminate the risk for cancer. [omicsonline.org]

These mutations are associated with low blood levels of gonadotropin and sex steroid levels throughout life and with a high incidence of microphallus, cryptorchidism and small testes, which can be observed during the neonatal period. [edmcasereports.com]
Males with hypogonadotropic hypogonadism are often born with an unusually small penis (micropenis) and undescended testes (cryptorchidism). They also present with delayed or incomplete puberty. [hormones.gr]

Workup
Diagnosis [ edit ] Diagnosing KS and other forms of CHH is complicated by the difficulties in distinguishing between a normal constitutional delay of puberty or a case of KS/CHH. [27] [4] [28] The diagnosis is often one of exclusion found during the workup [en.wikipedia.org]

Prognosis
Finally in silico studies from Gene Expression Omnibus and The Cancer Genome Atlas databases indicates that those NSCLC patients with low expression of DUSP6 are those with the worst prognosis. [cancerres.aacrjournals.org]
Prognosis Many forms of hypogonadism are potentially treatable and have a good prognosis. Prevention People should maintain normal body weight and have healthy eating habits to prevent anorexia nervosa. Other causes may not be preventable. [encyclopedia.com]
Early detection of the disease can significantly improve prognosis. [centogene.com]
