Genes affected

COL6A4P1 (HGNC:):

COL6A4P1 (HGNC:33484): (collagen type VI alpha 4 pseudogene 1) This transcribed pseudogene represents the 5' end of a presumed ortholog to a mouse gene which encodes a collagen VI alpha 4 chain protein (GeneID 68553). No complete ORF of comparable size to the mouse protein is found in this gene. The predicted protein lacks a signal peptide; however, this truncated collagen polypeptide may have achieved a different function as suggested by PubMed ID: 18622395. Evidence of in vivo translation is incomplete. A large chromosome break separates this pseudogene from the 3' end of the presumed ortholog (COL6A4P2, GeneID 646300) which is located downstream at chromosome 3q21.3. [provided by RefSeq, Jun 2009]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.48).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.474 is higher than 0.05.
