Genes affected

PROP1 (HGNC:9455): (PROP paired-like homeobox 1) This gene encodes a paired-like homeodomain transcription factor in the developing pituitary gland. Expression occurs prior to and is required for expression of pou domain transcription factor 1, which is responsible for pituitary development and hormone expression. Mutations in this gene have been associated with combined pituitary hormone deficiency-2 as well as deficiencies in luteinizing hormone, follicle-stimulating hormone, growth hormone, prolactin, and thyroid-stimulating hormone.

The c.655C>T (p.L219F) alteration is located in exon 3 (coding exon 3) of the PROP1 gene. This alteration results from a C to T substitution at nucleotide position 655, causing the leucine (L) at amino acid position 219 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
