Nablus mask-like facial syndrome (NMLFS) is a rare condition characterized by unique facial features, initially described in a 4-year-old boy from Nablus, Palestine. These features include expressionless facial appearance, tight facial skin, blepharophimosis, sparse eyebrows, and a flat nose. Genetic studies have identified a deletion of 8q22.

Fraser syndrome (MIM#219000) is an autosomal recessive disorder, characterized by the association of cryptophthtalmos, syndactyly of the four extremities, urinary tract abnormalities and laryngo-tracheal anomalies. This condition is due to homozygous or compound heterozygous mutations in the FRAS/FREM complex genes: FRAS1, FREM2 and GRIP1. Here we report two atypical cases of Fraser syndrome due to mutations in the FRAS1 gene without cryptophthalmos.

Gonadal sex determination is a complex genetic process by which an embryonic primordium is driven to form an ovary or a testis, which requires a delicate dosage balance involving many genes. Disruption in this molecular pathway can lead to differences of sex development (DSD). Although some genetic mechanisms leading to 46,XY DSD have been elucidated, little is known about copy-number variation (CNV) causing testicular or ovotesticular 46,XX DSD.

Turner syndrome is a sex chromosome abnormality in which a female has a single X chromosome or structurally deficient second sex chromosome. The phenotypic spectrum is broad, and atypical features prompt discussion of whether the known features of Turner syndrome should be further expanded. With the advent of clinical whole exome sequencing, there has been increased realization that some patients with genetic disorders carry a second genetic disorder, leading us to hypothesize that a "dual diagnosis" may be more common than suspected for Turner syndrome.
