Genes affected

SCOC (HGNC:20335): (short coiled-coil protein) This gene encodes a short coiled-coiled domain-containing protein that localizes to the Golgi apparatus. The encoded protein interacts with ADP-ribosylation factor-like proteins. Pseudogenes of this gene are found on chromosomes 1 and 14. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

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

The c.266A>C (p.E89A) alteration is located in exon 3 (coding exon 3) of the SCOC gene. This alteration results from a A to C substitution at nucleotide position 266, causing the glutamic acid (E) at amino acid position 89 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
