Invitae | RCV000536108 | SCV000625089 | pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2017-12-22 | criteria provided, single submitter | clinical testing | This sequence change affects a donor splice site in intron 14 of the MLH1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant has been reported in the literature in an individual affected with Lynch syndrome (PMID: 26248088). A different variant affecting this nucleotide (c.1667+1G>T) has been determined to be pathogenic in a family affected with Lynch syndrome (PMID: 21642682). This suggests that this nucleotide is important for normal RNA splicing, and that other variants at this position may also be pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in MLH1 are known to be pathogenic (PMID: 15713769, 24362816). For these reasons, this variant has been classified as Pathogenic. |
