Genes affected

OGFOD1 (HGNC:25585): (2-oxoglutarate and iron dependent oxygenase domain containing 1) Enables peptidyl-proline 3-dioxygenase activity. Involved in several processes, including peptidyl-proline hydroxylation; regulation of translational termination; and stress granule assembly. Located in cytoplasmic stress granule; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

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=0.34170192).

The c.383C>G (p.S128C) alteration is located in exon 4 (coding exon 4) of the OGFOD1 gene. This alteration results from a C to G substitution at nucleotide position 383, causing the serine (S) at amino acid position 128 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
