Genes affected

HLTF (HGNC:11099): (helicase like transcription factor) This gene encodes a member of the SWI/SNF family. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein contains a RING finger DNA binding motif. Two transcript variants encoding the same protein have been found for this gene. However, use of an alternative translation start site produces an isoform that is truncated at the N-terminus compared to the full-length protein. [provided by RefSeq, Jul 2008]

The c.2549C>T (p.P850L) alteration is located in exon 22 (coding exon 22) of the HLTF gene. This alteration results from a C to T substitution at nucleotide position 2549, causing the proline (P) at amino acid position 850 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
