Genes affected

MIXL1 (HGNC:13363): (Mix paired-like homeobox) Enables RNA polymerase II-specific DNA-binding transcription factor binding activity and sequence-specific double-stranded DNA binding activity. Predicted to be involved in several processes, including endodermal cell differentiation; hematopoietic progenitor cell differentiation; and positive regulation of mesoderm development. Predicted to act upstream of or within cell migration involved in gastrulation and hemopoiesis. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.304G>C (p.E102Q) alteration is located in exon 1 (coding exon 1) of the MIXL1 gene. This alteration results from a G to C substitution at nucleotide position 304, causing the glutamic acid (E) at amino acid position 102 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
