PMS2 mutations in childhood cancer.
Until recently, the PMS2 DNA mismatch repair gene has only rarely been implicated as a cancer susceptibility locus. New studies have shown, however, that earlier analyses of this gene have had technical limitations and also that the genetic behavior of mutant PMS2 alleles is unusual, in that, unlike MLH1 or MSH2 mutations, PMS2 mutations show low heterozygote penetrance. As a result, a dominant...
متن کاملNovel Autosomal Recessive c10orf2 Mutations Causing Infantile-Onset Spinocerebellar Ataxia
Recessive mutations in genes encoding mitochondrial DNA replication machinery lead to mitochondrial DNA depletion syndromes. This genetically and phenotypically heterogeneous group includes infantile onset spinocerebellar ataxia (OMIM# 271245) a neurodegenerative disease caused by mutations in the mtDNA helicase gene, c10orf2, with an increased frequency in the Finnish population due to a found...
متن کاملMutations in SNX14 cause a distinctive autosomal-recessive cerebellar ataxia and intellectual disability syndrome.
Intellectual disability and cerebellar atrophy occur together in a large number of genetic conditions and are frequently associated with microcephaly and/or epilepsy. Here we report the identification of causal mutations in Sorting Nexin 14 (SNX14) found in seven affected individuals from three unrelated consanguineous families who presented with recessively inherited moderate-severe intellectu...
متن کاملMSH6 and PMS2 mutation positive Australian Lynch syndrome families: novel mutations, cancer risk and age of diagnosis of colorectal cancer
BACKGROUND Approximately 10% of Lynch syndrome families have a mutation in MSH6 and fewer families have a mutation in PMS2. It is assumed that the cancer incidence is the same in families with mutations in MSH6 as in families with mutations in MLH1/MSH2 but that the disease tends to occur later in life, little is known about families with PMS2 mutations. This study reports on our findings on mu...
متن کاملNovel mutations causing hyperimmunoglobulin D and periodic fever syndrome.
Hyperimmunoglobulin D and periodic fever syndrome (HIDS) is a rare, hereditary autoinflammatory condition characterized by recurrent inflammatory episodes. We report a 9-year-old boy, diagnosed with HIDS due to two novel mutations, c.62C>T (p.Ala21Val) and c.372-6T>C (probable splicing defect), in the mevalonate kinase (MVK) gene. The pathogenicity of these mutations was confirmed by measuremen...
