Genetic Variant RHBDD3:p.Ser253Thr (chr22-29260552-A-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_012265.3(RHBDD3):c.757T>A(p.Ser253Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000691 in 1,446,692 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign 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. S253P) has been classified as Uncertain significance.

Genes affected

RHBDD3 (HGNC:1308): (rhomboid domain containing 3) Predicted to enable serine-type endopeptidase activity. Predicted to be involved in proteolysis. Predicted to act upstream of or within several processes, including liver development; negative regulation of natural killer cell activation; and positive regulation of protein catabolic process. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
