Genes affected
TAGLN2 (HGNC:11554): (transgelin 2) The protein encoded by this gene is similar to the protein transgelin, which is one of the earliest markers of differentiated smooth muscle. The specific function of this protein has not yet been determined, although it is thought to be a tumor suppressor. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.541A>G (p.N181D) alteration is located in exon 5 (coding exon 4) of the TAGLN2 gene. This alteration results from a A to G substitution at nucleotide position 541, causing the asparagine (N) at amino acid position 181 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
