3 reviews

Eleanor Williams (Genomics England Curator)

Comment on list classification: Associated with Duane retraction syndrome 3 (MIM: 617041) and Multicentric carpotarsal osteolysis syndrome (MIM: 166300) in OMIM and Gene2Phenotype. Mental retardation and minor facial anomalies have been noted in some patients with Multicentric carpotarsal osteolysis syndrome in two papers from the late 1980s, PMID: 3591830 and 3041835 but haven't got access to those papers. No reports of intellectual disability phenotypes in more recent papers e.g. PMID: 23670161
