Genes affected

FLRT3 (HGNC:3762): (fibronectin leucine rich transmembrane protein 3) This gene encodes a member of the fibronectin leucine rich transmembrane protein (FLRT) family. FLRTs may function in cell adhesion and/or receptor signalling. Their protein structures resemble small leucine-rich proteoglycans found in the extracellular matrix. This gene is expressed in many tissues. Two alternatively spliced transcript variants encoding the same protein have been described for this gene. [provided by RefSeq, Jul 2010]

FLRT3 links:

MACROD2 (HGNC:16126): (mono-ADP ribosylhydrolase 2) The protein encoded by this gene is a deacetylase involved in removing ADP-ribose from mono-ADP-ribosylated proteins. The encoded protein has been shown to translocate from the nucleus to the cytoplasm upon DNA damage. [provided by RefSeq, May 2017]

The c.1865T>C (p.L622P) alteration is located in exon 3 (coding exon 1) of the FLRT3 gene. This alteration results from a T to C substitution at nucleotide position 1865, causing the leucine (L) at amino acid position 622 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
