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 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.31586742).

Dec 06, 2023

The c.958A>T (p.N320Y) alteration is located in exon 2 (coding exon 2) of the SCRT1 gene. This alteration results from a A to T substitution at nucleotide position 958, causing the asparagine (N) at amino acid position 320 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
