Genes affected

SLC25A32 (HGNC:29683): (solute carrier family 25 member 32) This gene encodes a member of the P(I/L)W subfamily of mitochondrial carrier family transport proteins. The encoded protein transports folate across the inner mitochondrial membrane. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2013]

SLC25A32 links:

DCAF13 (HGNC:24535): (DDB1 and CUL4 associated factor 13) Enables estrogen receptor binding activity. Predicted to be involved in maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Located in several cellular components, including centrosome; cytosol; and nuclear lumen. Part of Cul4-RING E3 ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Aug 28, 2023

The c.62T>G (p.V21G) alteration is located in exon 1 (coding exon 1) of the SLC25A32 gene. This alteration results from a T to G substitution at nucleotide position 62, causing the valine (V) at amino acid position 21 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
