Genes affected

FNBP4 (HGNC:19752): (formin binding protein 4) This gene encodes a protein containing two tryptophan-rich WW domains that binds the proline-rich formin homology 1 domains of formin family proteins, suggesting a role in the regulation of cytoskeletal dynamics during cell division and migration. It also binds intersectin family proteins suggesting a role in the maintenance of membrane curvature at sites of nascent vesicle formation. Naturally occurring mutations in this gene are associated with Waardenburg anophthalmia syndrome. [provided by RefSeq, Apr 2017]

Ambry Genetics

Mar 06, 2023

The c.2504T>C (p.I835T) alteration is located in exon 15 (coding exon 15) of the FNBP4 gene. This alteration results from a T to C substitution at nucleotide position 2504, causing the isoleucine (I) at amino acid position 835 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
