| 12q14 microdeletion syndrome is characterized by mild intellectual deficit, failure to thrive, short stature and osteopoikilosis. It has been described in four unrelated patients. The syndrome appears to be caused by a heterozygous deletion at chromosome region 12q14, which was detected in three of the four patients. The deleted region contains the LEMD3 gene: mutations in this gene have already been implicated in osteopoikilosis. |

| A rare difference of sex development due to reduced 17,20-lyase activity that affects individuals with 46,XY karyotype and is characterized by female or atypical external genitalia with reduced phallic size, hypospadias, incomplete fusion of the labioscrotal swellings, cryptorchidism, and a blind vaginal pouch. Blood pressure and electrolytes are normal whilst hormonal investigations show normal basal and stimulated levels of cortisol, and low basal and stimulated androgen levels. |

| A rare, genetic, developmental defect during embryogenesis disorder characterized by severe, early-onset, salt-wasting adrenal insufficiency and ambiguous/female external genitalia (irrespective of chromosomal sex) due to mutations in the CYP11A1 gene. Milder cases may present delayed onset of adrenal gland dysfunction and genitalia phenotype may range from normal male to female in individuals with 46,XY karyotype. Imaging studies reveal hypoplastic/absent adrenal glands and biochemical findings include low serum cortisol, mineralocorticoids, androgens, and sodium, with elevated potassium levels. |

| 46,XY gonadal dysgenesis-motor and sensory neuropathy syndrome is a rare, genetic, developmental defect during embryogenesis disorder characterized by partial (unilateral testis, persistence of Müllerian duct structures) or complete (streak gonads only) gonadal dysgenesis, usually manifesting with primary amenorrhea in individuals with female phenotype but 46,XY karyotype, and sensorimotor dysmyelinating minifascicular polyneuropathy, which presents with numbness, weakness, exercise-induced muscle cramps, sensory disturbances and reduced/absent deep tendon reflexes. Germ cell tumors (seminoma, dysgerminoma, gonadoblastoma) may develop from the gonadal tissue. |

| 46,XY ovotesticular disorder of sex development is a rare, genetic disorder of sex development characterized by either the coexistence of both male and female reproductive gonads or, more frequently, by the presence of one or both gonads containing a mixture of both testicular and ovarian tissue (ovotestes) in an individual with a normal male 46, XY karyotype. External genitalia are usually ambiguous but can range from normal male to normal female and if a uterus and/or fallopian tubes are present, they are generally hypoplastic. Cryptorchidism, hypospadias, infertility and increased risk of gonadal tumors are frequently associated. |

| A rare Y chromosome number anomaly that affects only males and is characterized by mild-moderate developmental delay (especially speech), normal to mild intellectual disability, large, irregular teeth with poor enamel, tall stature and acne. Radioulnar synostosis and clinodactyly have also been associated. Boys generally present normal genitalia, while hypogonadism and infertility are frequently reported in adult males. |

Skeletal abnormalities (such as skull deformities, radioulnar synostosis, elbow flexion, clinodactyly, brachydactyly) and behavioral problems have also been associated with this condition. Genitalia are normal at birth, although hypogonadism and azoospermia has been reported in adults. |
