Genes affected

DLEC1 (HGNC:2899): (DLEC1 cilia and flagella associated protein) The cytogenetic location of this gene is 3p21.3, and it is located in a region that is commonly deleted in a variety of malignancies. Down-regulation of this gene has been observed in several human cancers including lung, esophageal, renal tumors, and head and neck squamous cell carcinoma. In some cases, reduced expression of this gene in tumor cells is a result of aberrant promoter methylation. Several alternatively spliced transcripts have been observed that contain disrupted coding regions and likely encode nonfunctional proteins.[provided by RefSeq, Mar 2016]

The c.461G>A (p.R154K) alteration is located in exon 2 (coding exon 2) of the DLEC1 gene. This alteration results from a G to A substitution at nucleotide position 461, causing the arginine (R) at amino acid position 154 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
