Genes affected

MSH5 (HGNC:7328): (mutS homolog 5) This gene encodes a member of the mutS family of proteins that are involved in DNA mismatch repair and meiotic recombination. This protein is similar to a Saccharomyces cerevisiae protein that participates in segregation fidelity and crossing-over events during meiosis. This protein plays a role in promoting ionizing radiation-induced apoptosis. This protein forms hetero-oligomers with another member of this family, mutS homolog 4. Polymorphisms in this gene have been linked to various human diseases, including IgA deficiency, common variable immunodeficiency, and premature ovarian failure. Alternative splicing results multiple transcript variants. Read-through transcription also exists between this gene and the downstream chromosome 6 open reading frame 26 (C6orf26) gene.

MSH5 links:

MSH5-SAPCD1 (HGNC:41994): (MSH5-SAPCD1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring mutS homolog 5 (MSH5) and chromosome 6 open reading frame 26 (C6orf26) genes. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

The c.152A>G (p.H51R) alteration is located in exon 3 (coding exon 2) of the MSH5 gene. This alteration results from a A to G substitution at nucleotide position 152, causing the histidine (H) at amino acid position 51 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
