Genes affected

GEMIN6 (HGNC:20044): (gem nuclear organelle associated protein 6) GEMIN6 is part of a large macromolecular complex, localized to both the cytoplasm and the nucleus, that plays a role in the cytoplasmic assembly of small nuclear ribonucleoproteins (snRNPs). Other members of this complex include SMN (MIM 600354), GEMIN2 (SIP1; MIM 602595), GEMIN3 (DDX20; MIM 606168), GEMIN4 (MIM 606969), and GEMIN5 (MIM 607005).[supplied by OMIM, Jul 2002]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Ambry Genetics

Oct 14, 2023

The c.440C>G (p.S147C) alteration is located in exon 3 (coding exon 2) of the GEMIN6 gene. This alteration results from a C to G substitution at nucleotide position 440, causing the serine (S) at amino acid position 147 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
