Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2
The NM_001077415.3(CRELD1):c.119C>G(p.Pro40Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000805 in 1,613,986 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P40L) 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]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.119C>G (p.P40R) alteration is located in exon 1 (coding exon 1) of the CRELD1 gene. This alteration results from a C to G substitution at nucleotide position 119, causing the proline (P) at amino acid position 40 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
