Invitae | RCV002524250 | SCV002950304 | uncertain significance | not provided | 2022-07-12 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 407 of the PCNT protein (p.Asn407Ile). This variant is present in population databases (rs745322520, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with PCNT-related conditions. ClinVar contains an entry for this variant (Variation ID: 436177). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. |
Ambry Genetics | RCV002524251 | SCV003697621 | uncertain significance | Inborn genetic diseases | 2021-06-18 | criteria provided, single submitter | clinical testing | The c.1220A>T (p.N407I) alteration is located in exon 8 (coding exon 8) of the PCNT gene. This alteration results from a A to T substitution at nucleotide position 1220, causing the asparagine (N) at amino acid position 407 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV003962392 | SCV004784321 | uncertain significance | PCNT-related condition | 2023-11-08 | criteria provided, single submitter | clinical testing | The PCNT c.1220A>T variant is predicted to result in the amino acid substitution p.Asn407Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0058% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/21-47769610-A-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
