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]

The c.366G>A (p.M122I) alteration is located in exon 3 (coding exon 3) of the DHX40 gene. This alteration results from a G to A substitution at nucleotide position 366, causing the methionine (M) at amino acid position 122 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
