Genes affected

TEX38 (HGNC:29589): (testis expressed 38) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

TEX38 links:

ATPAF1 (HGNC:18803): (ATP synthase mitochondrial F1 complex assembly factor 1) This gene encodes an assembly factor for the F(1) component of the mitochondrial ATP synthase. This protein binds specifically to the F1 beta subunit and is thought to prevent this subunit from forming nonproductive homooligomers during enzyme assembly. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Aug 2011]

The c.39G>C (p.M13I) alteration is located in exon 2 (coding exon 2) of the TEX38 gene. This alteration results from a G to C substitution at nucleotide position 39, causing the methionine (M) at amino acid position 13 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
