ZAP70-Related Severe Combined Immunodeficiency Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 16, 2022 | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 207 of the ZAP70 protein (p.Thr207Met). This variant is present in population databases (rs141564129, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ZAP70-related conditions. ClinVar contains an entry for this variant (Variation ID: 546868). 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: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available"). 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. - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 02, 2021 | The c.620C>T (p.T207M) alteration is located in exon 5 (coding exon 3) of the ZAP70 gene. This alteration results from a C to T substitution at nucleotide position 620, causing the threonine (T) at amino acid position 207 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
