Genes affected
COL12A1 (HGNC:2188): (collagen type XII alpha 1 chain) This gene encodes the alpha chain of type XII collagen, a member of the FACIT (fibril-associated collagens with interrupted triple helices) collagen family. Type XII collagen is a homotrimer found in association with type I collagen, an association that is thought to modify the interactions between collagen I fibrils and the surrounding matrix. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -17 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.74).
BP6
Variant 6-75089146-A-G is Benign according to our data. Variant chr6-75089146-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 542509.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-1.1 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00154 (235/152232) while in subpopulation AFR AF= 0.00527 (219/41524). AF 95% confidence interval is 0.0047. There are 0 homozygotes in gnomad4. There are 96 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
