Ida Ertmanska changed review comment from: PMID: 37013901 Averdunk et al., 2023 Report of 2 probands diagnosed with Rothmund-Thomson syndrome, harbouring biallelic CRIPT variants. P1 - 4yo Moroccan female, homozygous for CRIPT: c.132del, p.Ala45Glnfs*86 P2 - 8yo Romanian male homozygous for CRIPT: c.227G>A, p.(Cys76Tyr) Both patients had facial rash, poikiloderma, sparse hair, short stature, syndactyly of toes, seizures, abnormal teeth, developmental delay, recurrent chest infections; P1 also had cataracts, dystrophic nails, and a proximally placed thumb; only P2 had microcephaly.

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. Sources: Literature |

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.
