Genetic Variant NM_022078.3:c.74G>T (chr1-26900369-C-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_022078.3(GPATCH3):c.74G>T(p.Arg25Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,744 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R25H) has been classified as Uncertain significance.

Genes affected

GPATCH3 (HGNC:25720): (G-patch domain containing 3) Predicted to enable nucleic acid binding activity. Involved in negative regulation of RIG-I signaling pathway; negative regulation of type I interferon production; and positive regulation of transcription, DNA-templated. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

GPATCH3 links:

NUDC (HGNC:8045): (nuclear distribution C, dynein complex regulator) This gene encodes a nuclear distribution protein that plays an essential role in mitosis and cytokinesis. The encoded protein is involved in spindle formation during mitosis and in microtubule organization during cytokinesis. Pseudogenes of this gene are found on chromosome 2.
