Added comment: Biallelic mutations in VPS11 cause Leukodystrophy, hypomyelinating, 12 (MIM 616683).

PMIDs: 27120463, 26307567, 27473128 all report on this disorder.

The phenotype consists of global DD, ID, (variable) acquired microcephaly with hypomyelination upon brain MRI. Seizures appear to be a feature in several individuals.

Almost all individuals appear to be of Ashkenazi Jewish descent, homozygous for a founder mutation (NM_021729.5:c.2536T>G or p.Cys846Gly). PMIDs: 27120463 and 26307567 report on 13 individuals from 7 Ashkenazi families.

A second variant (p.Leu387_Gly395del) was however found in the homozygous state in 2 sibs born to consanguineous parents. Seizures were also noted in these individuals.

Pathogenicity is supported by extensive functional studies in all relevant articles.

VPS11 is not associated with any phenotype in G2P.

As a result, this gene can be considered for inclusion in this panel probably as green (or amber).

[Please consider inclusion in the lysosomal disorders panel as well as in the undiagnosed metabolic disorders panel].
