Summaries for Ladd Syndrome

About this section
Genetics Home Reference:21 Lacrimo-auriculo-dento-digital (LADD) syndrome is a genetic disorder that mainly affects the eyes, ears, mouth, and hands. LADD syndrome is characterized by defects in the tear-producing lacrimal system (lacrimo-), ear problems (auriculo-), dental abnormalities (dento-), and deformities of the fingers (digital).

MalaCards based summary: Ladd Syndrome, also known as lacrimoauriculodentodigital syndrome, is related to fgf10-related lacrimo-auriculo-dento-digital syndrome and fgfr2-related lacrimo-auriculo-dento-digital syndrome, and has symptoms including overfolded helix, conductive hearing impairment and alacrima. An important gene associated with Ladd Syndrome is FGF10 (fibroblast growth factor 10), and among its related pathways are Angiogenesis and Akt Signaling Pathway. The compounds su 5402 and pd 161570 have been mentioned in the context of this disorder. Affiliated tissues include salivary gland, eye and skin, and related mouse phenotypes are limbs/digits/tail and hearing/vestibular/ear.

Disease Ontology:8 An autosomal dominant disease that is characterized by abnormalities affecting the lacrimal and salivary glands and ducts, ears, teeth and fingers and toes.

OMIM:46 Lacrimoauriculodentodigital syndrome is a multiple congenital anomaly disorder mainly affecting lacrimal glands and... (149730) more...
