RCV000803305 | SCV000943169 | uncertain significance | X-linked agammaglobulinemia with growth hormone deficiency | 2019-05-29 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with proline at codon 347 of the BTK protein (p.Ala347Pro). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed to segregate with X-linked agammaglobulinaemia in a family (PMID: 16712653). 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. |
