MLL2 V1432Shift - GET-Evidence

Note: This variant has not been sufficiently evaluated by a GET-Evidence editor.

To be considered sufficiently evaluated a variant must have both "variant evidence" and "clinical importance" scores filled in.

MLL2 V1432Shift

(MLL2 1432delVinsShift)


Short summary

Nonsense or frameshift alleles of this gene are associated with the autosomal dominant disease Kabuki syndrome. As PGP89 is not affected, this is likely a sequencing error.

Exome sequencing identifies MLL2 mutations as a cause of Kabuki syndrome. Nat Genet. 2010 Sep;42(9):790-3. doi: 10.1038/ng.646. Epub 2010 Aug 15.

Exome sequencing identifies nonsense or frameshift alleles in MLL2 associated with the autosomal dominant disease Kabuki syndrome. The majority of the cases identified carry de novo alleles (12/14).

PGP89 is scored as heterozygous for MLL2-V1432Shift but does not show symptoms of Kabuki syndrome. Frameshift alleles with lesions downstream of V1432 show the dominant phenotype (PMID: 20711175), so it is likely that this is a sequencing error.
