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]

Mar 31, 2024

The c.1511C>T (p.S504F) alteration is located in exon 12 (coding exon 12) of the DHX40 gene. This alteration results from a C to T substitution at nucleotide position 1511, causing the serine (S) at amino acid position 504 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
