BRANCHIOOTIC SYNDROME 1; BOS1

Overview

This report includes information about branchiootic syndrome 1 (BOS1), which is one of several related autosomal dominant diseases associated with the human gene EYA1; see the human disease model report for 'branchiootorenal spectrum disorders, EYA1-related' (see FBhh0000463).

Variant(s) implicated in human disease tested (as analogous mutation in fly gene): E528K in the fly eya gene [corresponds to E330K (E363K) in the human EYA1 gene; R715G in the fly eya gene [corresponds to R514G (R547G) in the human EYA1 gene]. It has been postulated that these two variants are associated with anterior segment anomalies manifesting in ocular disorders in humans, but supporting evidence is limited.

Human gene(s) implicated

[EYA TRANSCRIPTIONAL COACTIVATOR AND PHOSPHATASE 1; EYA1](https://omim.org/entry/601653)

Symptoms and phenotype

The phenotypic manifestations of branchiootorenal spectrum disorders are typically in the areas of the branchial arch, ear and kidney. For the implicated gene EYA1, some missense mutations may result in ocular defects (Azuma et al., 2000; pubmed:10655545).

(FlyBase Curators, 2013-)

Branchiootic syndrome (BOS) is characterized by sensorineural, conductive, or mixed hearing loss, structural defects of the outer, middle, and inner ear, and branchial fistulas or cysts; it is characterized by the same branchial and otic anomalies as those seen in individuals with the branchiootorenal syndrome (BOR1), but lacks renal anomalies (Vincent et al., 1997; pubmed:9359046).

(OMIM, 2013-)

Genetics

Branchiootic syndrome 1 (BOS1) is caused by heterozygous mutation in the EYA1 gene (autosomal dominant). [from MIM:602588; 2017.01.06]

Gene Snapshot

eyes absent (eya) encodes a transcriptional cofactor that physically interacts with several other retinal determination proteins, including those encoded by ey, dac, and so. The product of eya regulates eye, gonad, and brain development as well as axon pathfinding. [Date last reviewed: 2018-09-06]

Comments on ortholog(s)

Moderate- to high-scoring ortholog of human EYA1, EYA2, EYA3, and EYA4 (1 Drosophila to 4 human). Dmel\eya shares 39-45% identity and 51-58% similarity with the human genes.
