Genes affected

FBXO38 (HGNC:28844): (F-box protein 38) This gene encodes a large protein that contains an F-box domain and may participate in protein ubiquitination. The encoded protein is a transcriptional co-activator of Krueppel-like factor 7 (Klf7). A heterozygous mutation in this gene was found in individuals with autosomal dominant distal hereditary motor neuronopathy type IID. There is a pseudogene for this gene on chromosome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

The c.3536A>G (p.N1179S) alteration is located in exon 22 (coding exon 21) of the FBXO38 gene. This alteration results from a A to G substitution at nucleotide position 3536, causing the asparagine (N) at amino acid position 1179 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 1104 of the FBXO38 protein (p.Asn1104Ser). This variant is present in population databases (rs373082610, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with FBXO38-related conditions. ClinVar contains an entry for this variant (Variation ID: 581498). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
