Cystic kidney disease v8.15 TMEM17 Ida Ertmanska Tag Q2_26_promote_green tag was added to gene: TMEM17.
Cystic kidney disease v8.15 TMEM17 Ida Ertmanska Classified gene: TMEM17 as Amber List (moderate evidence)
Cystic kidney disease v8.15 TMEM17 Ida Ertmanska Added comment: Comment on list classification: There are at least 9 unrelated individuals (3 surviving individuals and 6 fetal cases) reported with biallelic TMEM17 variants and evidence of a multisystem ciliopathy (molar tooth sign, features supporting a diagnosis of Meckel syndrome, Joubert syndrome). More than 3 unrelated individuals had polycystic kidneys, as well as other renal findings. Hence, this gene should be promoted to Green at the next update.

Homozygous missense mutation reported in TMEM17 (p.Asn102Lys) in two siblings (both male, 20 yrs and 36yrs old whose clinical profile is consistent with Oral-Facial-Digital type 6 syndrome. Both patients had polydactyly, psychomotor delay; cerebellar hypoplasia and molar tooth sign also noted on brain imaging (see S2 table). Fibroblasts from a TMEM17-mutated sibling displayed a much reduced ability to form cilia compared to cells from the healthy heterozygous mother.

Homozygous variant NM_198276:c.302G > T; p.Gly101Val detected in a child with Joubert syndrome.

PMID: 40841990 Boutaud et al., 2025
Report of two unrelated fetuses with occipital encephalocele, polydactyly, and kidney cysts. Exome sequencing identified a founder homozygous missense variant c.280C>T, p.(Arg94Trp) in TMEM17. Both diagnosed with Meckel syndrome (severe ciliopathy).

Four unrelated patients were identified with a clinical diagnosis of Meckel-Gruber syndrome (MGS) - a severe, lethal ciliopathy - and novel homozygous TMEM17 variants: NM_198276.3 c.4del p.(Glu2Serfs*58); c.366dup p.(Pro123Thrfs*9); and c.368C>G p.(Pro123Arg). Severe prenatal phenotype: encephalocele, polycystic kidney dysplasia, and polydactyly, leading to early lethality.

This gene is not yet associated with a phenotype in OMIM, G2P, or ClinGen (accessed 22nd Apr 2026).
