Genes affected
CIAO3 (HGNC:14179): (cytosolic iron-sulfur assembly component 3) Predicted to enable 4 iron, 4 sulfur cluster binding activity. Involved in several processes, including iron-sulfur cluster assembly; oxygen homeostasis; and response to hypoxia. Part of CIA complex. [provided by Alliance of Genome Resources, Apr 2022]
HAGHL (HGNC:14177): (hydroxyacylglutathione hydrolase like) Predicted to enable hydroxyacylglutathione hydrolase activity and metal ion binding activity. Predicted to be involved in methylglyoxal catabolic process to D-lactate via S-lactoyl-glutathione. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1150C>T (p.R384C) alteration is located in exon 10 (coding exon 10) of the NARFL gene. This alteration results from a C to T substitution at nucleotide position 1150, causing the arginine (R) at amino acid position 384 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
