Genes affected

DHX40 (HGNC:18018): (DEAH-box helicase 40) This gene encodes a member of the DExH/D box family of ATP-dependent RNA helicases that have an essential role in RNA metabolism. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 17.[provided by RefSeq, Oct 2009]

Nov 17, 2022

The c.299T>C (p.M100T) alteration is located in exon 3 (coding exon 3) of the DHX40 gene. This alteration results from a T to C substitution at nucleotide position 299, causing the methionine (M) at amino acid position 100 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
