The tumor was found to have recurred 6 months later and was characterized as an anaplastic astrocytoma. While undergoing radiation treatment for the recurring brain tumor, T-cell lymphoma was detected. Despite treatment, the lymphoma infiltrated the heart, resulting in the patient's death. The boy's sister had cafe-au-lait spots by 3 months of age and developed a spinal cord glioblastoma at age 2 years that resulted in loss of ability to walk. At that time axillary freckling was noted. Ten months later she developed a brain tumor. She died 4 months later.

There was no family history of NF1 and no mutations were identified in the NF1 gene. Family history revealed a maternal grand-aunt with endometrial cancer at age 59 and several paternal relatives with possible colon polyps. Neoplastic colonic tissue from the surviving sister with polyps showed absence of the MSH6 protein and microsatellite instability. The proband had 11 adenomatous polyps 1 to 3 cm in diameter extending the entire length of the colon, some of which showed a high degree of dysplasia. She developed an oligodendroglioma at age 19 years, and at age 24 was found to have 2 synchronous colon adenocarcinomas, one in the cecum and the other in the transverse colon.

<strong>Description</strong>

</h4>
</div>
<span class="mim-text-font">
<p>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). </p><p>For a discussion of genetic heterogeneity of mismatch repair cancer syndrome, see MMRCS1 (276300).</p>

<strong>Clinical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Menko et al. (2004) reported a 10-year-old boy who presented with diplopia and headache due to a malignant oligodendroglioma in the mesencephalon which was treated by partial resection, radiotherapy, and chemotherapy. At age 12 years he developed adenocarcinoma of the rectosigmoid. Six cafe-au-lait spots were noted. He died at age 12 years due to brain tumor recurrence. </p><p>Hegde et al. (2005) studied 2 sibs from a Pakistani family, a boy with lymphoma and colorectal cancer diagnosed at ages 5 and 8 years, respectively, and his sister who developed glioblastoma multiforme at age 8 years. Both children had cafe-au-lait spots and axillary freckling. The boy died at age 9 years and the girl at age 10 years. Microsatellite instability assay performed on the glioblastoma from the sister indicated instability in more than 40% of markers tested compared to germline DNA. </p><p>Ostergaard et al. (2005) reported 2 sibs with a clinical diagnosis of NF1 who developed tumors of the central nervous system (CNS) at an early age. At age 9 years, the boy developed a pilocytic astrocytoma, which was resected. At that time cafe-au-lait spots and axillary freckling were noted. The tumor was found to have recurred 6 months later and was characterized as an anaplastic astrocytoma. While undergoing radiation treatment for the recurring brain tumor, T-cell lymphoma was detected. Despite treatment, the lymphoma infiltrated the heart, resulting in the patient's death. The boy's sister had cafe-au-lait spots by 3 months of age and developed a spinal cord glioblastoma at age 2 years that resulted in loss of ability to walk. At that time axillary freckling was noted. Ten months later she developed a brain tumor. She died 4 months later. Both sibs had a deficiency of IgA. </p><p>Auclair et al. (2007) reported a family in which 2 sisters had features suggestive of NF1, including cafe-au-lait spots and Lisch nodules, associated with fatal glioblastoma and adenomatous colonic polyps, respectively. There was no family history of NF1 and no mutations were identified in the NF1 gene. Family history revealed a maternal grand-aunt with endometrial cancer at age 59 and several paternal relatives with possible colon polyps. Neoplastic colonic tissue from the surviving sister with polyps showed absence of the MSH6 protein and microsatellite instability. The proband had 11 adenomatous polyps 1 to 3 cm in diameter extending the entire length of the colon, some of which showed a high degree of dysplasia. She developed an oligodendroglioma at age 19 years, and at age 24 was found to have 2 synchronous colon adenocarcinomas, one in the cecum and the other in the transverse colon. She died 1 year later from rapid malignant evolution. </p><p>Poley et al. (2007) studied a boy of Moroccan descent with non-Hodgkin lymphoma, oligodendroglioma, and cafe-au-lait spots. The lymphoma and oligodendroglioma both showed low microsatellite instability and absence of staining for the MSH6 protein. Normal tissue was also MSH6-negative. Further genetic analysis could not be performed. A brother with cafe-au-lait spots had died of medulloblastoma at age 8 years. </p>

<strong>Molecular Genetics</strong>

</h4>
</div>
<span class="mim-text-font">
<p>In a boy with childhood onset of malignant oligodendroglioma, colonic adenocarcinoma, and cafe-au-lait spots, Menko et al. (2004) identified a homozygous mutation in the MSH6 gene (600678.0014). No germline mutations were identified in the NF1 gene. Both of the boy's consanguineous healthy parents carried the mutation. </p><p>In a Pakistani girl with glioblastoma multiforme and early death, Hegde et al. (2005) identified a homozygous mutation in the MSH6 gene (600678.0015). Her brother had colonic adenocarcinoma and lymphoma, but DNA was not available for testing. </p><p>In 2 sibs with brain tumor-polyposis syndrome, Ostergaard et al. (2005) identified compound heterozygosity for 2 mutations in the MSH6 gene (600678.0012, 600678.0013). A boy developed an anaplastic astrocytoma at age 9.4 years and later developed a T-cell lymphoma. His sister had a glioblastoma of the spinal cord at age 2 years. Both children had multiple cafe-au-lait spots without other features of NF1. Three additional heterozygous family members had colon and/or endometrial cancer. Ostergaard et al. (2005) concluded that the phenotype of cafe-au-lait spots, hematologic malignancies, and glioma results from a lack of activity of the mismatch repair (MMR) complex. The NF1-like features likely result from somatic mutations in the NF1 gene secondary to MMR deficiency. </p><p>In a girl with MMRCS3 who had multiple adenomatous colonic polyps with a high degree of dysplasia at the age of 9 years, as well as cafe-au-lait spots and Lisch nodules, Auclair et al. (2007) identified compound heterozygous mutations in the MSH6 gene (600678.0016, 600678.0017). </p>
