| Invitae | RCV003763755 | SCV001210128 | uncertain significance | Ichthyosis linearis circumflexa | 2023-11-27 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 360 of the SPINK5 protein (p.Ala360Thr). This variant is present in population databases (rs529385811, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with SPINK5-related conditions. ClinVar contains an entry for this variant (Variation ID: 843576). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SPINK5 protein function with a negative predictive value of 80%. 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 | RCV002553138 | SCV003630909 | uncertain significance | Inborn genetic diseases | 2022-06-24 | criteria provided, single submitter | clinical testing | The c.1078G>A (p.A360T) alteration is located in exon 12 (coding exon 12) of the SPINK5 gene. This alteration results from a G to A substitution at nucleotide position 1078, causing the alanine (A) at amino acid position 360 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
