Genes affected

CGNL1 (HGNC:25931): (cingulin like 1) This gene encodes a member of the cingulin family. The encoded protein localizes to both adherens and tight cell-cell junctions and mediates junction assembly and maintenance by regulating the activity of the small GTPases RhoA and Rac1. Heterozygous chromosomal rearrangements resulting in association of the promoter for this gene with the aromatase gene are a cause of aromatase excess syndrome. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Nov 2011]

The c.331C>T (p.P111S) alteration is located in exon 2 (coding exon 1) of the CGNL1 gene. This alteration results from a C to T substitution at nucleotide position 331, causing the proline (P) at amino acid position 111 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
