Genes affected

RWDD3 (HGNC:21393): (RWD domain containing 3) Involved in negative regulation of NF-kappaB transcription factor activity; positive regulation of hypoxia-inducible factor-1alpha signaling pathway; and positive regulation of protein sumoylation. Predicted to be located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TLCD4-RWDD3 (HGNC:49388): (TLCD4-RWDD3 readthrough) This locus represents naturally occurring read-through transcription between the neighboring TMEM56 (transmembrane protein 56) and RWDD3 (RWD domain containing 3) genes on chromosome 1. The read-through transcript encodes a protein that shares sequence identity with the upstream gene product, but it contains a distinct C-terminus due to frameshifts versus the downstream gene coding sequence.

ENSG00000228852 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.46).
• BP7: Synonymous conserved (PhyloP=0.219 with no splicing effect.
