Genes affected

DUXA (HGNC:32179): (double homeobox A) Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. This gene is a member of the DUXA homeobox gene family. Evidence of mRNA expression has not yet been found for this gene. Multiple, related processed pseudogenes have been found which are thought to reflect expression of this gene in the germ line or embryonic cells. [provided by RefSeq, Jul 2008]

Feb 05, 2024

The c.313C>T (p.R105C) alteration is located in exon 4 (coding exon 4) of the DUXA gene. This alteration results from a C to T substitution at nucleotide position 313, causing the arginine (R) at amino acid position 105 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
