Genes affected
GAS1 (HGNC:4165): (growth arrest specific 1) Growth arrest-specific 1 plays a role in growth suppression. GAS1 blocks entry to S phase and prevents cycling of normal and transformed cells. Gas1 is a putative tumor suppressor gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.944G>A (p.R315H) alteration is located in exon 1 (coding exon 1) of the GAS1 gene. This alteration results from a G to A substitution at nucleotide position 944, causing the arginine (R) at amino acid position 315 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
