H3F3A
h3f3a: A Genetic Variant with Far-Reaching Implications
Description
The h3f3a gene encodes the H3F3A protein, a histone that plays a crucial role in regulating gene expression. Alterations in the h3f3a gene can disrupt this regulatory process, leading to a wide range of developmental disorders and diseases.
Associated Diseases
Mutations in h3f3a have been linked to several genetic conditions, including:
- Weaver syndrome: A rare disorder characterized by accelerated growth, distinctive facial features, intellectual disability, and characteristic hand and foot deformities.
- Simpson-Golabi-Behmel syndrome: A complex malformation syndrome involving overgrowth, intellectual disability, cardiac anomalies, and characteristic facial features.
- Perlman syndrome: A condition characterized by short stature, intellectual disability, microcephaly (small head size), and distinctive facial features.
- Hoyeraal-Hreidarsson syndrome: A rare disorder involving short stature, skeletal abnormalities, intellectual disability, and distinctive facial features.
- Intellectual disability: Mutations in h3f3a have been associated with intellectual disability of varying degrees.
Did you Know ?
Approximately 1 in 100,000 newborns are affected by Weaver syndrome, making it one of the most common genetic causes of accelerated growth.
