Genes affected
NOA1 (HGNC:28473): (nitric oxide associated 1) The protein encoded by this gene is a nuclear-encoded GTPase that functions in the mitochondrion. Upon translation, this protein is imported into the nucleus and then into the nucleolus before being exported to the mitochondrion. The encoded protein is required for oxygen-dependent regulation of mitochondrial respiratory complexes and for mitochondrial protein synthesis. [provided by RefSeq, Dec 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 03, 2023The c.1365T>A (p.F455L) alteration is located in exon 3 (coding exon 3) of the NOA1 gene. This alteration results from a T to A substitution at nucleotide position 1365, causing the phenylalanine (F) at amino acid position 455 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
