Genes affected
SLTM (HGNC:20709): (SAFB like transcription modulator) Enables RNA binding activity. Predicted to be involved in regulation of mRNA processing and regulation of transcription by RNA polymerase II. Located in nuclear body. [provided by Alliance of Genome Resources, Apr 2022]
RNF111 (HGNC:17384): (ring finger protein 111) The protein encoded by this gene is a nuclear RING-domain containing E3 ubiquitin ligase. This protein interacts with the transforming growth factor (TGF) -beta/NODAL signaling pathway by promoting the ubiquitination and proteosomal degradation of negative regulators, like SMAD proteins, and thereby enhances TGF-beta target-gene transcription. As a modulator of the nodal signaling cascade, this gene plays a critical role in the induction of mesoderm during embryonic development. Alternative splicing of this gene results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.2377C>T (p.R793W) alteration is located in exon 18 (coding exon 18) of the SLTM gene. This alteration results from a C to T substitution at nucleotide position 2377, causing the arginine (R) at amino acid position 793 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
