Eleanor Williams changed review comment from: Associated with Hamamy syndrome #611174 (AR) in OMIM. Hamamy syndrome is characterised by craniofacial dysmorphism, hearing loss, skeletal anomalies, microcytic hypochromic anemia and congenital heart defects. Severe myopia has also been reported. Homozygous missense variants in IRX5 were reported in 2 families with this condition. Cone dystrophy ------------------- PMID: 33891002 - Khol et al 2021 - report 3 unrelated families with duplications of a region covering the genes IRX5 and IRX6 completely, and the proximal exons of MMP2 and cone dystrophy. They propose that overexpression of IRX5 and IRX6 may be the cause of the disease, and this is supported by expression analysis in patient-derived fibroblasts and zebrafish experiments. Initial family is a large 5 generation German family with 14 members with autosomal dominant cone dystrophy in which a 600kb duplicated region covering IRX5/IRX6 and part of MMP2 was identified. 2 additional families of Chinese and Dutch descent with copy number gains of ~700 and ~850 kb, covering the same region were then identified. The smallest region of overlap is 608kb. In addition another family of German decent is reported with adCD and the same duplication as the first German family. It is not known if they are distantly related. Segregation analysis on available members of all families showed the duplication in affected members and not in unaffected. They find that IRX5, IRX6 and MMP2 are expressed in human adult retina. Several lincRNA within the locus are also expressed. In patient derived fibroblasts IRX5 and IRX6 showed increased expression levels. Over expression of IRX5 and IRX6 results in impaired visual performance in zebrafish larvae.; to: Associated with Hamamy syndrome #611174 (AR) in OMIM.

Loss of function/gene --------- PMID: 28041643 - Carss et al 2017 - screened a cohort of 722 individuals with inherited retinal disease using WES/WGS. 1 case reported with a biallelic deletion in IRX5 reported which leads to a frameshift ENST00000394636.4; c.1362_1366delTAAAG, p.Lys455ProfsTer19 in a patient with retinitis pigmentosa. PMID: 32045705 - Apuzzo et al 2020 - report 2 cases of loss of a region in 16q12.1q21 which encompasses IRX5 and IRX6 and many other genes, which together with 3 other previous reports of deletions in this region help define a syndrome with features that include dysmorphic features, short stature, microcephaly, global developmental delay/intellectual disability, autism spectrum disorder (ASD) and ocular abnormalities (nystagmus and strabismus). |
