Genes affected

PITX1 (HGNC:9004): (paired like homeodomain 1) This gene encodes a member of the RIEG/PITX homeobox family, which is in the bicoid class of homeodomain proteins. Members of this family are involved in organ development and left-right asymmetry. This protein acts as a transcriptional regulator involved in basal and hormone-regulated activity of prolactin.

Ambry Genetics

Jun 22, 2024

The c.20G>T (p.G7V) alteration is located in exon 1 (coding exon 1) of the PITX1 gene. This alteration results from a G to T substitution at nucleotide position 20, causing the glycine (G) at amino acid position 7 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
