Genes affected

SLC25A30 (HGNC:27371): (solute carrier family 25 member 30) Although the outer mitochondrial membrane is permeable to many small metabolites, transport of solutes across the inner mitochondrial membrane is achieved by members of the mitochondrial carrier protein family, such as SLC25A30 (Haguenauer et al., 2005 [PubMed 15809292]).[supplied by OMIM, Mar 2008]

TPT1-AS1 (HGNC:43686): (TPT1 antisense RNA 1) Biomarker of malignant astrocytoma. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.042053252).

The c.116C>A (p.T39K) alteration is located in exon 3 (coding exon 2) of the SLC25A30 gene. This alteration results from a C to A substitution at nucleotide position 116, causing the threonine (T) at amino acid position 39 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
