Genes affected

(HGNC:):

SCRG1 (HGNC:17036): (stimulator of chondrogenesis 1) Scrapie-responsive gene 1 is associated with neurodegenerative changes observed in transmissible spongiform encephalopathies. It may play a role in host response to prion-associated infections. The scrapie responsive protein 1 may be partly included in the membrane or secreted by the cells due to its hydrophobic N-terminus. In addition, the encoded protein can interact with bone marrow stromal cell antigen 1 (BST1) to enhance the differentiation potentials of human mesenchymal stem cells during tissue and bone regeneration.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.518 is higher than 0.05.
