| Cytopenias and congenital anaemias v1.79 | RAP1B |
Ivone Leong gene: RAP1B was added gene: RAP1B was added to Cytopenias and congenital anaemias. Sources: Literature watchlist tags were added to gene: RAP1B. Mode of inheritance for gene: RAP1B was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: RAP1B were set to 32627184; 26280580 Phenotypes for gene: RAP1B were set to Syndromic intellectual disability; cytopenia Review for gene: RAP1B was set to AMBER Added comment: This gene is associated with a phenotype in Gene2Phenotype but not OMIM. PMID: 32627184 describes 2 patients. 36 yo patient of non-consanguineous parents. Had unclear pancytopenia, multiple congenital malformations, mild intellectual disability, endocrine disorders (short stature with growth hormone deficiency), dysmorphism and other features. Parents and sibling unaffected. 13 yo of non-consanguineous parents with thrombocytopenia, multiple congenital anomalies and learning difficulties. He had normal developmental milestones, walk was achieved at 14 months and there was no speech delay. He attended mainstream school with auxiliary help because of learning difficulties with graphism, syntaxic comprehension, logical reasoning and attention deficit. Parents and siblings unaffected. PMID: 26280580 describes another patient with variant in RAP1B. The clinical features can be found in supplementary table 2. The table lists ID, but doesn't say severity and lists a host of other features including short stature, facial dysmorphism and skeletal findings. Cytopenia is not a feature for this patient. All 3 cases seem to have a very wide spectrum of differing phenotypes and therefore, this gene has been given an Amber rating until further evidence is available. Sources: Literature |
