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 -15 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.43).
BP6
Variant 6-75089110-G-A is Benign according to our data. Variant chr6-75089110-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 475908.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.037 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000657 (100/152154) while in subpopulation AMR AF= 0.00654 (100/15296). AF 95% confidence interval is 0.0055. There are 1 homozygotes in gnomad4. There are 65 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
