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 -19 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.35).
BP6
Variant 6-75146183-C-T is Benign according to our data. Variant chr6-75146183-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 259332.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.714 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000157 (230/1461368) while in subpopulation MID AF= 0.00364 (21/5764). AF 95% confidence interval is 0.00244. There are 2 homozygotes in gnomad4_exome. There are 119 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 2 AD,AR gene
