Genes affected
TUSC1 (HGNC:31010): (tumor suppressor candidate 1) This gene is located within the region of chromosome 9p that harbors tumor suppressor genes critical in carcinogenesis. It is an intronless gene which is downregulated in non-small-cell lung cancer and small-cell lung cancer cell lines, suggesting that it may play a role in lung tumorigenesis.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2022The c.550C>T (p.P184S) alteration is located in exon 1 (coding exon 1) of the TUSC1 gene. This alteration results from a C to T substitution at nucleotide position 550, causing the proline (P) at amino acid position 184 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
