Mendeliome v1.1978 TMEM216 Zornitza Stark Tag founder tag was added to gene: TMEM216.
Tag UTR tag was added to gene: TMEM216.
Mendeliome v1.1978 TMEM216 Zornitza Stark edited their review of gene: TMEM216: Added comment: PMID 39191256: Two rare nucleotide substitutions at the same genomic location on chromosome 11 (g.61392563 [GRCh38]), 69 base pairs upstream of the start codon of the ciliopathy gene TMEM216 (c.-69G>A, c.-69G>T [GenBank: NM_001173991.3]) found in individuals of South Asian and African ancestry, respectively.

This included 71 homozygotes and 3 mixed heterozygotes in trans with a predicted loss-of-function allele. Haplotype analysis showed single-nucleotide variants (SNVs) common across families, suggesting ancestral alleles within the two distinct ethnic populations.

Clinical phenotype analysis of 62 available individuals from 49 families indicated a similar clinical presentation with night blindness in the first decade and progressive peripheral field loss thereafter. No evident systemic ciliopathy features were noted.

Functional characterization of these variants by luciferase reporter gene assay showed reduced promotor activity.; Changed publications: 20036350, 20512146, 39191256; Changed phenotypes: Joubert syndrome 2, MIM# 608091, MONDO:0011963, Meckel syndrome 2, MIM# 603194, MONDO:0011296, Retinitis pigmentosa, MONDO:0019200, TMEM216-related
