Genes affected

GLRX5 (HGNC:20134): (glutaredoxin 5) This gene encodes a mitochondrial protein, which is evolutionarily conserved. It is involved in the biogenesis of iron-sulfur clusters, which are required for normal iron homeostasis. Mutations in this gene are associated with autosomal recessive pyridoxine-refractory sideroblastic anemia. [provided by RefSeq, May 2010]

GLRX5 links:

SNHG10 (HGNC:27510): (small nucleolar RNA host gene 10) This gene is small nucleolar RNA host gene 10 and represents a non-protein coding RNA. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2013]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.41G>T (p.R14L) alteration is located in exon 1 (coding exon 1) of the GLRX5 gene. This alteration results from a G to T substitution at nucleotide position 41, causing the arginine (R) at amino acid position 14 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

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. 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: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with GLRX5-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 14 of the GLRX5 protein (p.Arg14Leu). -
