Genes affected

GSTCD (HGNC:25806): (glutathione S-transferase C-terminal domain containing) Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

INTS12 (HGNC:25067): (integrator complex subunit 12) INTS12 is a subunit of the Integrator complex, which associates with the C-terminal domain of RNA polymerase II large subunit (POLR2A; MIM 180660) and mediates 3-prime end processing of small nuclear RNAs U1 (RNU1; MIM 180680) and U2 (RNU2; MIM 180690) (Baillat et al., 2005 [PubMed 16239144]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0499039).

The c.360C>A (p.D120E) alteration is located in exon 2 (coding exon 1) of the GSTCD gene. This alteration results from a C to A substitution at nucleotide position 360, causing the aspartic acid (D) at amino acid position 120 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
