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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.72).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000178 (27/152002) while in subpopulation AMR AF= 0.000851 (13/15274). AF 95% confidence interval is 0.000503. There are 1 homozygotes in gnomad4. There are 16 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
