Additional Information:

Clinical Description OMIM Pignata et al. (1996) reported 2 sisters with an association of congenital alopecia, severe T-cell immunodeficiency, and ridging and pitting of all nails. A decrease of mature T lymphocytes was mainly due to a low number of helper ...
Molecular genetics OMIM In the 2 sisters described by Pignata et al. (1996), Frank et al. (1999) identified homozygosity for a mutation (R255X; 600838.0001) in FOXN1 gene. The sister who had received a bone marrow transplant from her brother was alive ...
Population genetics OMIM Adriani et al. (2004) reported 4 additional children from the same Italian community reported by Pignata et al. (1996) and Frank et al. (1999) who were affected with congenital alopecia and died from severe infections in early childhood. ...
