Fetal anomalies v0.3701 HECW2 Zornitza Stark Marked gene: HECW2 as ready
Fetal anomalies v0.3701 HECW2 Zornitza Stark Gene: hecw2 has been classified as Red List (Low Evidence).
Fetal anomalies v0.3701 HECW2 Zornitza Stark Phenotypes for gene: HECW2 were changed from HECW2 to Neurodevelopmental disorder with hypotonia, seizures, and absent language (MIM#617268)
Fetal anomalies v0.3700 HECW2 Zornitza Stark Publications for gene: HECW2 were set to
Fetal anomalies v0.3699 HECW2 Zornitza Stark Mode of pathogenicity for gene: HECW2 was changed from to Other
Fetal anomalies v0.3698 HECW2 Zornitza Stark Mode of inheritance for gene: HECW2 was changed from MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Fetal anomalies v0.3697 HECW2 Zornitza Stark changed review comment from: Typically denovo missense variants in the HECT domain.
PMID: 29807643 - R1191Q single case with severe D/ID, EE and regression
PMID: 29395664 - single case with regression, loss of swallowing, increased abnormal movements/hand stereotypies, Rett like, cortical visual impairment and EE
PMID: 27334371 - propose GOF or dominant negative; 1 case plus references 5 previous cases
PMID: 27389779 - four novel de novo predicted deleterious missense variants in HECW2 in six probands with ID/developmental delay and hypotonia. Other common features include seizures, strabismus, nystagmus, cortical visual impairment and dysmorphic facial features. p. Arg1330Trp, p.Glu1445Gly reported >1 case.
Regression reported in the context of refractory EE; to: Clinical presentation is typically post-natal.
