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.

Jun 02, 2023

The c.67C>T (p.P23S) alteration is located in exon 1 (coding exon 1) of the PITX1 gene. This alteration results from a C to T substitution at nucleotide position 67, causing the proline (P) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
