Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_014391.3(ANKRD1):c.944G>C(p.Arg315Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000992 in 1,613,700 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R315C) has been classified as Uncertain significance.

Uncertain significance, no assertion criteria provided | provider interpretation | Stanford Center for Inherited Cardiovascular Disease, Stanford University | Nov 10, 2016 | -p.Arg315Pro (R315P) (CGC>CCC): c.944 G>C in exon 9 of the ANKRD1 gene (NM_014391.2) Given the lack of case data and the presence of several variants occurring at a relatively high rate in control populations in the same codon, we consider this variant to be a variant of unknown significance, likely benign, and we do not feel it is suitable for assessing risk in healthy relatives ("predictive genetic testing"). Testing other affected family members, if available, for the purposes of segregation analysis may assist with further interpretation. We have seen this variant in an individual with DCM. This variant did not segregate with disease in another family member with idiopathic LV dysfunction, though other non-genetic causes of LV dysfunction have not been ruled out as this time. The variant has not been reported in ClinVar or in the literature (as of 1/10/16). Codon 315 is the second to last codon of the protein. The laboratory report notes that in silico analysis with SIFT and PolyPhen-2 predict the variant to be neutral, but Mutation Taster predicts it to be deleterious. The Arginine at codon 315 is conserved among mammals. Neighboring amino acids are conserved in primates, but not in the cat or mouse. An allelic variant p.Arg315His has been reported in ClinVar by GeneDx and interpreted as a variant of unknown significance. No pathogenic variants have been reported at nearby codons. The nearest likely pathogenic variant reported in ClinVar is at residue 287. Although this particular amino acid substitution is not listed, there is variation at codon 315 listed in the Exome Aggregation Consortium dataset (http://exac.broadinstitute.org/), which currently includes variant calls on ~64,000 individuals of European, African, Latino and Asian descent (as of 1/10/2016). The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. Specifically, a total of 3 other missense variants have been observed in codon 315, two allelic variants at the second position of the codon (10: 92672639) and one variant at the next base in the third position of the codon (10: 92672640). Therefore, 1 in 6,070 individuals have missense variation at codon 315. The allelic variant p.Arg315His was observed in 7 of 60,204 individuals (6 of 5,789 people of Latino ancestry and 1 person of non-Finnish European ancestry). Another allelic p.Arg315Leu variant was observed in 2 of 60,204 individuals (2 of 33,369 people of non-Finnish European ancestry). Both of these variants were predicted to be benign and tolerated by Polyphen and SIFT, respectively. A third variant affecting same codon p.Arg315Leu was observed in 2 of 60,204 individuals (2 of 33,369 people of non-Finnish European ancestry). This variant was predicted to be possibly damaging by Polyphen and deleterious by SIFT. - |
ANKRD1-related dilated cardiomyopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Dec 26, 2023 | This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 315 of the ANKRD1 protein (p.Arg315Pro). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ANKRD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 518679). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 12, 2022 | The c.944G>C (p.R315P) alteration is located in exon 9 (coding exon 9) of the ANKRD1 gene. This alteration results from a G to C substitution at nucleotide position 944, causing the arginine (R) at amino acid position 315 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
