Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 16, 2021 | The c.251C>T (p.T84M) alteration is located in exon 3 (coding exon 3) of the NECAP1 gene. This alteration results from a C to T substitution at nucleotide position 251, causing the threonine (T) at amino acid position 84 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |

Developmental and epileptic encephalopathy, 21 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 01, 2022 | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 84 of the NECAP1 protein (p.Thr84Met). This variant is present in population databases (rs137964265, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with NECAP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 475005). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. - |
