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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), FBXO38. . Gene score misZ 2.8126 (greater than the threshold 3.09). Trascript score misZ 3.83 (greater than threshold 3.09). GenCC has associacion of gene with distal hereditary motor neuropathy type 2, neuronopathy, distal hereditary motor, type 2D, distal hereditary motor neuropathy.
BP4
Computational evidence support a benign effect (MetaRNN=0.083765596).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2019The p.N14K variant (also known as c.42T>G), located in coding exon 1 of the FBXO38 gene, results from a T to G substitution at nucleotide position 42. The asparagine at codon 14 is replaced by lysine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
