Genes affected
PRL (HGNC:9445): (prolactin) This gene encodes the anterior pituitary hormone prolactin. This secreted hormone is a growth regulator for many tissues, including cells of the immune system. It may also play a role in cell survival by suppressing apoptosis, and it is essential for lactation. Alternative splicing results in multiple transcript variants that encode the same protein.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.227G>T (p.R76L) alteration is located in exon 3 (coding exon 3) of the PRL gene. This alteration results from a G to T substitution at nucleotide position 227, causing the arginine (R) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
