Genes affected

FLRT1 (HGNC:3760): (fibronectin leucine rich transmembrane protein 1) This gene encodes a member of the fibronectin leucine rich transmembrane protein (FLRT) family. The family members may function in cell adhesion and/or receptor signalling. Their protein structures resemble small leucine-rich proteoglycans found in the extracellular matrix. The encoded protein shares sequence similarity with two other family members, FLRT2 and FLRT3. This gene is expressed in kidney and brain. [provided by RefSeq, Jul 2008]

MACROD1 (HGNC:29598): (mono-ADP ribosylhydrolase 1) Enables ADP-ribosylglutamate hydrolase activity and deacetylase activity. Involved in cellular response to DNA damage stimulus; peptidyl-glutamate ADP-deribosylation; and purine nucleoside metabolic process. Located in nucleoplasm.

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.035230517).
