Low match PROGRESSIVE MYOCLONIC EPILEPSY TYPE 7

A rare, genetic, neurological disorder characterized by childhood to adolescent onset of progressive myoclonus (which becomes very severe and results in major motor impediment) associated with infrequent tonic-clonic seizures, and, occasionally, ataxia. Learning disability prior to seizure onset and mild cognitive decline may be associated.

Low match PERIODIC FEVER, MENSTRUAL CYCLE-DEPENDENT

Women show menstrual cycle-dependent physiologic changes in relation to sex hormone levels. Because ovulation triggers a significant change in the hormonal milieu that is similar to local inflammation, a 0.5 to 1.0 degree Celsius increase in basal body temperature after ovulation is commonly associated with progesterone secretion and is believed to be triggered by the induction of several inflammatory cytokines. Rare menstrual cycle-dependent febrile episodes have been reported, some of which have shown a luteal-phase-dependent pattern (summary by Jiang et al., 2012).

Low match ABETALIPOPROTEINEMIA; ABL

Abetalipoproteinemia and familial hypobetalipoproteinemia (FBHL ) are rare diseases characterized by hypocholesterolemia and malabsorption of lipid-soluble vitamins leading to retinal degeneration, neuropathy, and coagulopathy. Hepatic steatosis is also common. The root cause of both disorders is improper packaging and secretion of apolipoprotein B-containing particles. Obligate heterozygous parents of ABL patients usually have normal lipids consistent with autosomal recessive inheritance, whereas obligate heterozygous parents of FBHL patients typically have half normal levels of apoB-containing lipoproteins consistent with autosomal codominant inheritance (summary by Lee and Hegele, 2014).

Ribose-5-P isomerase deficiency is an extremely rare, hereditary, disorder of pentose phosphate metabolism characterized by progressive leukoencephalopathy and a highly increased ribitol and D-arabitol levels in the brain and body fluids. Clinical presentation includes psychomotor delay, epilepsy, and childhood-onset slow neurological regression with ataxia, spasticity, optic atrophy and sensorimotor neuropathy.

Low match PANCREATIC CANCER

Pancreatic cancer shows among the highest mortality rates of any cancer, with a 5-year relative survival rate of less than 5%. By the time of initial diagnosis, metastatic disease is commonly present. Established risk factors include a family history of pancreatic cancer, a medical history of diabetes type 2, and cigarette smoking (summary by Amundadottir et al., 2009). Genetic Heterogeneity of Pancreatic CancerSomatic mutations in pancreatic cancer occur in the KRAS (OMIM ), CDKN2A (OMIM ), MADH4 (OMIM ), TP53 (OMIM ), ARMET (OMIM ), STK11 (OMIM ), ACVR1B (OMIM ), and RBBP8 (OMIM ) genes.Susceptibility loci for pancreatic cancer include PNCA1 (OMIM ), related to mutation in the PALLD gene on chromosome 4q32 (OMIM ); PNCA2 (OMIM ), related to mutation in the BRCA2 gene on chromosome 13q12 (OMIM ); PNCA3 (OMIM ), related to mutation in the PALB2 gene on chromosome 16p12 (OMIM ); and PNCA4 (OMIM ), related to mutation in the BRCA1 gene on chromosome 17q21 (OMIM ). Occurrence of Pancreatic Cancer in Other DisordersSeveral familial cancer syndromes increase the risk of pancreatic cancer. The best characterized include hereditary nonpolyposis colon cancer syndrome (HNPCC; see {120435}); hereditary breast-ovarian cancer syndrome due to mutations in BRCA2; Peutz-Jeghers syndrome (OMIM ); the melanoma-pancreatic cancer syndrome (OMIM ), caused by mutations in CDKN2A (OMIM ); von Hippel-Lindau syndrome (OMIM ), ataxia-telangiectasia (OMIM ) (Swift et al., 1976), and juvenile polyposis syndrome (OMIM ).Patients with hereditary pancreatitis (OMIM ) resulting from gain-of-function mutations in the protease serine-1 gene (PRSS1 ) have a lifetime pancreatic cancer risk ratio of 57 and a cumulative incidence, to age 70 years, of 40% (Lowenfels et al., 1997).
