Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3
The NM_001077415.3(CRELD1):c.524G>C(p.Arg175Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R175Q) has been classified as Uncertain significance.
CRELD1 (HGNC:14630): (cysteine rich with EGF like domains 1) This gene encodes a member of a subfamily of epidermal growth factor-related proteins. The encoded protein is characterized by a cysteine-rich with epidermal growth factor-like domain. This protein may function as a cell adhesion molecule. Mutations in this gene are the cause of atrioventricular septal defect. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Apr 2010]
PRRT3 (HGNC:26591): (proline rich transmembrane protein 3) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
