Lucy Spencer gene: TMEM184B was added gene: TMEM184B was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: TMEM184B was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown Publications for gene: TMEM184B were set to 39006436 Phenotypes for gene: TMEM184B were set to Neurodevelopmental disorder (MONDO:0700092), TMEM184B-related Review for gene: TMEM184B was set to GREEN Added comment: A cohort of 6 patients with developmental delay (5/6), corpus callosum hypoplasia (4/6), microcephaly (1/6), seizures (3/6), and ID (2/6). 2 patients also had gastrointestinal motility disruption. All 6 have de novo variants in TMEM184B, 5 missense 1 canonical splice. 1 of the missense variants has 35 hets in gnomad but the rest are absent. The authors also say they are aware of a 7th patient with overlapping features by personal communication. A knockout zebrafish model showed a dose dependent reduction in head size and body length in larvae. Knock-in of 2 of the missense variants also showed head size and body length reduction, but the other missense did not. However the other three missense failed to rescue the phenotype of a knockout zebrafish while WT and a negative control did. The authors suggest the first 2 variants are dominant negative while the latter three and loss of function. The splice variant was shown to cause exon 7 skipping which is out of frame. Transfection of the missense and splice variants in HEK293T cells showed that all but 1 had reduced TMEM184B protein levels. Sources: Literature |
