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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.24664748).

The c.2578G>C (p.D860H) alteration is located in exon 18 (coding exon 18) of the SLTM gene. This alteration results from a G to C substitution at nucleotide position 2578, causing the aspartic acid (D) at amino acid position 860 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
