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 GeneticsFeb 21, 2024The c.1502C>T (p.T501I) alteration is located in exon 14 (coding exon 14) of the FMNL2 gene. This alteration results from a C to T substitution at nucleotide position 1502, causing the threonine (T) at amino acid position 501 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
