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]

Ambry Genetics

Aug 02, 2021

The c.895C>T (p.R299C) alteration is located in exon 10 (coding exon 10) of the FMNL2 gene. This alteration results from a C to T substitution at nucleotide position 895, causing the arginine (R) at amino acid position 299 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
