Genes affected
TLCD3A (HGNC:29646): (TLC domain containing 3A) The protein encoded by this gene is a membrane-associated protein that promotes lung carcinogenesis. The encoded protein may be involved in amino acid transport and glutathione metabolism since it can interact with a solute carrier family member (SLC3A2) and an isoform of gamma-glutamyltranspeptidase-like 3. An alternatively spliced variant encoding a protein that lacks a 32 aa internal segment showed the opposite effect, inhibiting lung cancer cell growth. Knockdown of this gene also inhibited lung carcinogenesis and tumor cell growth. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.40G>A (p.G14R) alteration is located in exon 1 (coding exon 1) of the FAM57A gene. This alteration results from a G to A substitution at nucleotide position 40, causing the glycine (G) at amino acid position 14 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
