Cryptorchidism, and Pancytopenia

Fanconi anemia of complementation group P is an autosomal recessive disorder characterized by increased chromosomal instability and progressive bone marrow failure. Some patients have skeletal anomalies (summary by Kim et al., 2011).For a general description and a discussion of genetic heterogeneity of Fanconi anemia (FA), see {227650}.

Deafness-intellectual disability syndrome, Martin-Probst type is characterised by severe bilateral deafness, intellectual deficit, umbilical hernia and abnormal dermatoglyphics. It has been described in three males from three generations of one family. Mild facial dysmorphism (telangiectasias, hypertelorism, dental anomalies and a wide nasal root) was also present. Short stature, pancytopaenia, microcephaly, and renal and genitourinary anomalies were present in some of the patients. The mode of transmission is X-linked recessive and the causative gene has been localised to the q1-21 region of the X chromosome.

Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder that causes genomic instability. Characteristic clinical features include developmental abnormalities in major organ systems, early-onset bone marrow failure, and a high predisposition to cancer. The cellular hallmark of FA is hypersensitivity to DNA crosslinking agents and high frequency of chromosomal aberrations pointing to a defect in DNA repair (summary by Deakyne and Mazin, 2011).For additional general information and a discussion of genetic heterogeneity of Fanconi anemia, see {227650}.

Dyskeratosis congenita is an inherited bone marrow failure syndrome classically characterized by the triad of mucosal leukoplakia, nail dysplasia, and abnormal skin pigmentation. Affected individuals have an increased risk of aplastic anemia and malignancy. Less common features include epiphora, premature gray hair, microcephaly, developmental delay, and pulmonary fibrosis, among others. The phenotype is highly variable. All affected individuals have shortened telomeres due to a defect in telomere maintenance (summary by Savage et al., 2008).For a discussion of genetic heterogeneity of dyskeratosis congenita, see DCKA1 (OMIM ).

Seckel syndrome is a rare autosomal recessive disorder characterized by intrauterine growth retardation, dwarfism, microcephaly with mental retardation, and a characteristic 'bird-headed' facial appearance (Shanske et al., 1997). Genetic Heterogeneity of Seckel SyndromeOther forms of Seckel syndrome include SCKL2 (OMIM ), caused by mutation in the RBBP8 gene (OMIM ) on chromosome 18q11; SCKL4 (OMIM ), caused by mutation in the CENPJ gene (OMIM ) on chromosome 13q12; SCKL5 (OMIM ), caused by mutation in the CEP152 gene (OMIM ) on chromosome 15q21; SCKL6 (OMIM ), caused by mutation in the CEP63 gene (OMIM ) on chromosome 3q22; SCKL7 (OMIM ), caused by mutation in the NIN gene (OMIM ) on chromosome 14q22; SCKL8 (OMIM ), caused by mutation in the DNA2 gene (OMIM ) on chromosome 10q21; SCKL9 (OMIM ), caused by mutation in the TRAIP gene (OMIM ) on chromosome 3p21; and SCKL10 (OMIM ), caused by mutation in the NSMCE2 gene (OMIM ) on chromosome 8q24.The report of a Seckel syndrome locus on chromosome 14q, designated SCKL3, by Kilinc et al. (2003) was found to be in error; see HISTORY.
