Genes affected

REPIN1 (HGNC:17922): (replication initiator 1) Enables RNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of glucose import and regulation of fatty acid transport. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

REPIN1-AS1 (HGNC:41201): (REPIN1 antisense RNA 1)

ZNF775 (HGNC:28501): (zinc finger protein 775) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM1: In a modified_residue N6-acetyllysine (size 0) in uniprot entity REPI1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08062771).

Ambry Genetics

Nov 20, 2023

The c.97C>A (p.P33T) alteration is located in exon 2 (coding exon 1) of the REPIN1 gene. This alteration results from a C to A substitution at nucleotide position 97, causing the proline (P) at amino acid position 33 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
