Genes affected

ID4 (HGNC:5363): (inhibitor of DNA binding 4) This gene encodes a member of the inhibitor of DNA binding (ID) protein family. The encoded protein lacks DNA binding ability, and instead regulates gene expression through binding to and inhibiting basic helix-loop-helix transcription factors. This protein has been implicated in the regulation of diverse cellular processes that play a role in development and tumorigenesis. [provided by RefSeq, Aug 2017]

LNC-LBCS (HGNC:54418): (lncRNA bladder and prostate cancer suppressor, hnRNPK interacting)

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.437A>C (p.D146A) alteration is located in exon 1 (coding exon 1) of the ID4 gene. This alteration results from a A to C substitution at nucleotide position 437, causing the aspartic acid (D) at amino acid position 146 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
