Skeletal dysplasia v1.215 TMEM67 Eleanor Williams Classified gene: TMEM67 as Red List (low evidence)
Skeletal dysplasia v1.215 TMEM67 Eleanor Williams Added comment: Comment on list classification: After consultation with the Genomics England clinical team demoting this gene to red as the skeletal phenotype is not strong.
Skeletal dysplasia v1.215 TMEM67 Eleanor Williams Gene: tmem67 has been classified as Red List (Low Evidence).
Skeletal dysplasia v1.204 TMEM67 Eleanor Williams changed review comment from: Associated with several phenotypes in OMIM but ?RHYNS syndrome (#609884) is the main disease phenotype that has a skeletal component. Polydactyly may also be seen in Meckel syndrome 3 (#607361).

RHYNS syndrome - 1 case:

PMID: 9375913 - Di Rocco et al. (1997) - 1 case. 17.5-year-old boy with short stature, severe bone-age retardation and exhibited mild signs of skeletal dysplasia, including generalized osteopenia, epiphyseal hypoplasia, hypoplastic iliac bones with irregular acetabular margins, and thin tubular bones. He later developed nephronophthisis. Brancati et al. (2018) (PMID: 29891882) re-assessed this patient at age 38 years and reported he exhibited short stature and severe generalized osteoporosis. Skeletal survey showed moderately shortened long bones, bowed radii, short femoral neck, brachydactyly of the hands and feet with more severe involvement of middle phalanges, distal phalanx of the thumbs, and metacarpals, moderately thickened calvarium, and rotoscoliosis. Compound heterozygous variants in TMEM67 were identified, one inherited from each of his parents.

PMID: 11391657 - Hedera and Gorski (2001) described 2 brothers, who had early onset retinitis pigmentosa, short stature with GH deficiency, mild facial asymmetry, and acromelic shortening of the distal extremities. They suggest this phenotype is consistent with RHYNS syndrome but no genome analysis was done.

Meckel syndrome 3 - 3 out of 22 cases show polydactyly:

PMID: 16415887 - Smith et al. 2006 - detected 5 different homozygous mutations in the TMEM67 in 5 consanguineous families with Meckel syndrome. The mutations were not found in over 120 ethnically matched normal control chromosomes. Polydactyly was observed in 2 out of the 5 families.

PMID: 17377820 - Consugar et al. 2007 - identified 7 novel pathogenic mutations in the TMEM67 gene in 5 of 17 families with a clinical diagnosis of Meckel syndrome. All cases were compound heterogygous. Polydactyly is reported in 1 family.; to: Associated with several phenotypes in OMIM but ?RHYNS syndrome (#609884) is the main disease phenotype that has a skeletal component. Polydactyly may also be seen in Meckel syndrome 3 (#607361).
