Genes affected
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. [provided by RefSeq, Dec 2010]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2024The c.580C>A (p.R194S) alteration is located in exon 8 (coding exon 7) of the TMEM56-RWDD3 gene. This alteration results from a C to A substitution at nucleotide position 580, causing the arginine (R) at amino acid position 194 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
