Genes affected
SUPV3L1 (HGNC:11471): (Suv3 like RNA helicase) Enables helicase activity; nucleic acid binding activity; and protein homodimerization activity. Involved in several processes, including mitochondrial RNA metabolic process; mitochondrion morphogenesis; and positive regulation of mitochondrial RNA catabolic process. Located in mitochondrial nucleoid and nucleus. Part of mitochondrial degradosome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.443T>C (p.I148T) alteration is located in exon 3 (coding exon 3) of the SUPV3L1 gene. This alteration results from a T to C substitution at nucleotide position 443, causing the isoleucine (I) at amino acid position 148 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
