Genes affected

SCRT1 (HGNC:15950): (scratch family transcriptional repressor 1) This gene encodes a C2H2-type zinc finger transcriptional repressor that binds to E-box motifs. The encoded protein may promote neural differention and may be involved in cancers with neuroendocrine features. [provided by RefSeq, Jul 2013]

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=0.09138006).

The c.460G>C (p.G154R) alteration is located in exon 2 (coding exon 2) of the SCRT1 gene. This alteration results from a G to C substitution at nucleotide position 460, causing the glycine (G) at amino acid position 154 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
