- Function
- Possesses dinucleoside triphosphate hydrolase activity (PubMed:12574506, PubMed:15182206, PubMed:8794732, PubMed:9323207, PubMed:9576908, PubMed:9543008). Cleaves P(1)-P(3)-bis(5'-adenosyl) triphosphate (Ap3A) to yield AMP and ADP (PubMed:12574506, PubMed:15182206, PubMed:8794732, PubMed:9323207, PubMed:9576908, PubMed:9543008). Can also hydrolyze P(1)-P(4)-bis(5'-adenosyl) tetraphosphate (Ap4A), but has extremely low activity with ATP (PubMed:8794732). Exhibits adenylylsulfatase activity, hydro... (Source: Uniprot)

Sebat et al (2007) searched for de novo CNVs in patients with autism. DNA samples were prepared from blood and/or immortalized B cells. Two independent de novo deletions involving FHIT were detected. Of note, one of these was detected in DNA derived from the patient's cell line, but not detected in DNA derived from the same patient's blood sample.

Girirajan et al (2013) studied CNVs in patients with autistic features. Deletions involving FHIT exons were identified in two patients and also in two controls.
HI Evidence Comments:
FHIT is located at a fragile site and is commonly deleted in cancer (e.g. PMIDs 11902576 and 29748005).

Fry et al (2016) studied CNVs in patients with intellectual disability or developmental delay and epilepsy. A paternally-inherited duplication involving the FHIT gene was observed in one patient. That same patient also had a de novo deletion involving CACNA1B and EHMT1.
