Limb disorders v2.37 KCNN3 Arina Puzriakova gene: KCNN3 was added
gene: KCNN3 was added to Limb disorders. Sources: Literature
Q2_21_rating tags were added to gene: KCNN3.
Mode of inheritance for gene: KCNN3 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: KCNN3 were set to 31155282; 33594261
Phenotypes for gene: KCNN3 were set to Zimmermann-Laband syndrome 3, OMIM:618658; Zimmermann-laband syndrome 3, MONDO:0032854
Mode of pathogenicity for gene: KCNN3 was set to Loss-of-function variants (as defined in pop up message) DO NOT cause this phenotype - please provide details in the comments
Review for gene: KCNN3 was set to GREEN
Added comment: Associated with 'Zimmermann-Laband syndrome' in OMIM (MIM# 618658) and Gene2Phenotype ('probable' disease confidence rating).

At least 6 unrelated individuals with different gain-of-function KCNN3 variants (PMIDs: 31155282 and 33594261). Phenotypes include mild-to-moderate DD and/or ID, coarse facial features, gingival enlargement, distal digital hypoplasia and hypertrichosis. Radial ray defects mostly within the milder end of the spectrum but do include hypoplasia of the terminal phalanges and aplasia/hypoplasia of nails on hands and feet.

Limb disorders v1.43 GZF1 Eleanor Williams Phenotypes for gene: GZF1 were changed from to Joint laxity, short stature, and myopia, 617662; Larsen syndrome
Limb disorders v1.42 GZF1 Eleanor Williams changed review comment from: Associated with Joint laxity, short stature, and myopia (#617662) in OMIM and Larsen syndrome (probable) in Gene2Phenotype.

PMID: 28475863 - Patel et al 2017 - 2 cases. Family 1 - a multiplex consanguineous Saudi family affected by severe and recurrent large joint dislocation and severe myopia. The index patient also had severe kyphoscoliosis. Both the index patient and her brother had short stature. A homozygous truncating variant in GZF1 was identified (c.865G>T (pGlu289∗). Family 2 - another multiplex consanguineous family affected by severe myopia, retinal detachment, and milder skeletal involvement (generalized joint laxity). A second homozygous truncating GZF1 variant was identified (c.1054dup (p.Thr352Asnfs∗50). Neither variant was present in 2,379 Saudi exomes or the Exome Aggregation Consortium (ExAC) Browser. In functional studies they found using immunofluorescence, strong localization of GZF1 in the developing mouse eye and, to a lesser extent, in the mesenchyme of the developing mouse limb buds. Using 3 patient-derived lymphoblastoid cell lines they found 1,095 genes to be dysregulated in affected individuals.; to: Associated with Joint laxity, short stature, and myopia (#617662) in OMIM and Larsen syndrome (probable) in Gene2Phenotype.

The index patient also had severe kyphoscoliosis. Both the index patient and her brother had short stature and bilateral talipes equinovarus deformity. A homozygous truncating variant in GZF1 was identified (c.865G>T (pGlu289∗).
