GARD : ²⁰ Wiedemann-Steiner syndrome (WSS) includes distinctive facial features, growth delay, and intellectual disability. Signs and symptoms vary, but facial features may include thick eyebrows, wide-spaced eyes, and narrow eye openings. People with WSS may also have excessive hair on the elbows, arms, and back; difficulty feeding; behavior problems; and seizures. Because WSS has been reported in a small number of individuals, there is not much information on how the symptoms and features change over time. WSS is caused by genetic changes in the KMT2A gene. Most individuals with WSS are the only ones in their family with this condition. In a few cases, WSS has been inherited in an autosomal dominant pattern. Diagnosis is based on the symptoms and clinical exam, and it is confirmed by the results of genetic testing. Treatment is focused on managing the symptoms.

MalaCards based summary : Wiedemann-Steiner Syndrome, also known as wdsts, is related to hypertrichosis and kabuki syndrome 1. An important gene associated with Wiedemann-Steiner Syndrome is KMT2A (Lysine Methyltransferase 2A), and among its related pathways/superpathways are Basal transcription factors and Chromatin Regulation / Acetylation. Affiliated tissues include eye and bone, and related phenotypes are delayed speech and language development and dysphagia

OMIM® : ⁵⁷ Wiedemann-Steiner syndrome is a congenital malformation syndrome characterized by hypertrichosis cubiti associated with short stature; consistent facial features, including long eyelashes, thick or arched eyebrows with a lateral flare, broad nasal bridge, and downslanting and vertically narrow palpebral fissures; mild to moderate intellectual disability; behavioral difficulties; and hypertrichosis on the back (summary by Jones et al., 2012 and Miyake et al., 2016).

KEGG : ³⁶ Wiedemann-Steiner Syndrome (WDSTS) is a rare autosomal dominant disorder characterized by hairy elbows, dysmorphic facial appearances (hypertelorism, thick eyebrows, downslanted and vertically narrow palpebral fissures), pre- and post-natal growth deficiency, and psychomotor delay. Sharing clinical features with Cornelia de Lange syndrome, WDSTS is another heterogeneous disease. WDSTS is caused by heterozygous mutations in KMT2A, also known as MLL. KMT2A encodes a histone methyltransferase that plays an important role in early development and hematopoiesis. Recently, an autosomal-recessive disorder with Cornelia de Lange syndrome-like features has been reported and termed Alazami-Yuan syndrome. It is caused by homozygous mutations in TAF6, which encodes a core transcriptional regulatory pathway component.

UniProtKB/Swiss-Prot : ⁷³ Wiedemann-Steiner syndrome: A syndrome characterized by hairy elbows (hypertrichosis cubiti), intellectual disability, a distinctive facial appearance, and short stature. Facial characteristics include long eyelashes, thick or arched eyebrows with a lateral flare, and downslanting and vertically narrow palpebral fissures.
