Genes affected

SLC25A37 (HGNC:29786): (solute carrier family 25 member 37) SLC25A37 is a solute carrier localized in the mitochondrial inner membrane. It functions as an essential iron importer for the synthesis of mitochondrial heme and iron-sulfur clusters (summary by Chen et al., 2009 [PubMed 19805291]).[supplied by OMIM, Jan 2011]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.978

The c.614T>C (p.L205P) alteration is located in exon 4 (coding exon 4) of the SLC25A37 gene. This alteration results from a T to C substitution at nucleotide position 614, causing the leucine (L) at amino acid position 205 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
