Genes affected

FMNL2 (HGNC:18267): (formin like 2) This gene encodes a formin-related protein. Formin-related proteins have been implicated in morphogenesis, cytokinesis, and cell polarity. Alternatively spliced transcript variants encoding different isoforms have been described but their full-length nature has yet to be determined. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.568T>G (p.S190A) alteration is located in exon 6 (coding exon 6) of the FMNL2 gene. This alteration results from a T to G substitution at nucleotide position 568, causing the serine (S) at amino acid position 190 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
