Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PP2PP5BP4BS2_Supporting

The NM_138455.4(CTHRC1):c.131A>C(p.Gln44Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0001 in 1,533,038 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q44H) has been classified as Uncertain significance.

Genes affected

CTHRC1 (HGNC:18831): (collagen triple helix repeat containing 1) This locus encodes a protein that may play a role in the cellular response to arterial injury through involvement in vascular remodeling. Mutations at this locus have been associated with Barrett esophagus and esophageal adenocarcinoma. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.63347 (below the threshold of 3.09). Trascript score misZ: 0.39942 (below the threshold of 3.09). GenCC associations: The gene is linked to Barrett esophagus.

PP5

Variant 8-103371787-A-C is Pathogenic according to our data. Variant chr8-103371787-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 30848.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr8-103371787-A-C is described in Lovd as [Likely_pathogenic].

BP4

Computational evidence support a benign effect (MetaRNN=0.093295276). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAd4 at 15 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
