Genes affected

ENAH (HGNC:18271): (ENAH actin regulator) This gene encodes a member of the enabled/ vasodilator-stimulated phosphoprotein. Members of this gene family are involved in actin-based motility. This protein is involved in regulating the assembly of actin filaments and modulates cell adhesion and motility. Alternate splice variants of this gene have been correlated with tumor invasiveness in certain tissues and these variants may serve as prognostic markers. A pseudogene of this gene is found on chromosome 3. [provided by RefSeq, Sep 2016]

The c.1391C>T (p.T464I) alteration is located in exon 9 (coding exon 9) of the ENAH gene. This alteration results from a C to T substitution at nucleotide position 1391, causing the threonine (T) at amino acid position 464 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
