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.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1381G>A (p.A461T) alteration is located in exon 2 (coding exon 1) of the FLRT1 gene. This alteration results from a G to A substitution at nucleotide position 1381, causing the alanine (A) at amino acid position 461 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. ClinVar contains an entry for this variant (Variation ID: 530934). This variant has not been reported in the literature in individuals affected with FLRT1-related conditions. This variant is present in population databases (rs138289564, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 461 of the FLRT1 protein (p.Ala461Thr). -
