Genes affected

ACVR1B (HGNC:172): (activin A receptor type 1B) This gene encodes an activin A type IB receptor. Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I and two type II receptors. This protein is a type I receptor which is essential for signaling. Mutations in this gene are associated with pituitary tumors. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jun 2010]

The c.862G>T (p.A288S) alteration is located in exon 5 (coding exon 5) of the ACVR1B gene. This alteration results from a G to T substitution at nucleotide position 862, causing the alanine (A) at amino acid position 288 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
