Genetic Variant CRELD2:p.Arg33Trp (chr22-49918866-C-T) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_024324.5(CRELD2):c.97C>T(p.Arg33Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000536 in 1,305,994 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R33G) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.97C>T (p.R33W) alteration is located in exon 1 (coding exon 1) of the CRELD2 gene. This alteration results from a C to T substitution at nucleotide position 97, causing the arginine (R) at amino acid position 33 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
