Genes affected
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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.050768048).
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000131 (2/152216) while in subpopulation SAS AF = 0.000414 (2/4832). AF 95% confidence interval is 0.0000729. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces arginine with threonine at codon 383 of the CRELD1 protein (p.Arg383Thr). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and threonine. In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant is present in population databases (rs748476213, ExAC 0.01%) but has not been reported in the literature in individuals with a CRELD1-related disease. -
