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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2024The c.2174C>T (p.P725L) alteration is located in exon 13 (coding exon 13) of the FNBP4 gene. This alteration results from a C to T substitution at nucleotide position 2174, causing the proline (P) at amino acid position 725 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
