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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.1260T>G (p.I420M) alteration is located in exon 13 (coding exon 13) of the FMNL2 gene. This alteration results from a T to G substitution at nucleotide position 1260, causing the isoleucine (I) at amino acid position 420 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
