Clinical summary

Help

Imported from OMIM

Mismatch repair cancer syndrome-3 (MMRCS3) is an autosomal recessive childhood cancer predisposition syndrome characterized by brain tumors, hematologic malignancy, and gastrointestinal tumors. Multiple cafe-au-lait spots, axillary freckling, and, rarely, Lisch nodules reminiscent of neurofibromatosis type I (NF1; 162200) may be present (Hegde et al., 2005, Ostergaard et al., 2005). Microsatellite instability may be detected in tumor samples (Hegde et al., 2005). For a discussion of genetic heterogeneity of mismatch repair cancer syndrome, see MMRCS1 (276300).

Clinical validity

Help

This panel should be performed in all individuals suspected of having an overlapping clinical phenotype. Confirmation of a clinical diagnosis through genetic testing can allow for genetic counseling and may direct medical management. Genetic counseling can provide a patient and/or family with the natural history of the condition, identify at-risk family members, provide reproductive risks as well as preconception/prenatal options, and allow for appropriate referral for patient support and/or resources.
