Genes affected

EDRF1 (HGNC:24640): (erythroid differentiation regulatory factor 1) This gene may play a role in erythroid cell differentiation. The encoded protein inhibits DNA binding of the erythroid transcription factor GATA-1 and may regulate the expression of alpha-globin and gamma-globin. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

Collection Method: clinical testing

The c.1262C>T (p.P421L) alteration is located in exon 10 (coding exon 10) of the EDRF1 gene. This alteration results from a C to T substitution at nucleotide position 1262, causing the proline (P) at amino acid position 421 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
