Variant summary

Our verdict is Benign. The variant received -18 ACMG points: 2P and 20B. PM1 BP4_Strong BP6_Very_Strong BA1

The NM_001854.4(COL11A1):​c.4603T>C​(p.Ser1535Pro) variant causes a missense change. The variant allele was found at a frequency of 0.802 in 1,612,246 control chromosomes in the GnomAD database, including 519,995 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1535L) has been classified as Uncertain significance.

Genes affected

COL11A1 (HGNC:2186): (collagen type XI alpha 1 chain) This gene encodes one of the two alpha chains of type XI collagen, a minor fibrillar collagen. Type XI collagen is a heterotrimer but the third alpha chain is a post-translationally modified alpha 1 type II chain. Mutations in this gene are associated with type II Stickler syndrome and with Marshall syndrome. A single-nucleotide polymorphism in this gene is also associated with susceptibility to lumbar disc herniation. Multiple transcript variants have been identified for this gene.

ACMG classification

Our verdict: Benign. The variant received -18 ACMG points.

• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 7 benign, 8 uncertain in NM_001854.4
• BP4: Computational evidence support a benign effect (MetaRNN=1.2520567E-6).
• BP6: Variant 1-102888582-A-G is Benign according to our data. Variant chr1-102888582-A-G is described in ClinVar as Benign. ClinVar VariationId is 17137.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.855 is higher than 0.05.
