Genes affected

HDGFL1 (HGNC:21095): (HDGF like 1) Predicted to enable double-stranded DNA binding activity and transcription coregulator activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

HDGFL1 links:

CASC15 (HGNC:28245): (cancer susceptibility 15) This gene produces a long non-coding RNA that may regulate cell proliferation. This RNA is upregulated in hepatocellular carcinoma, where it is thought to function as an oncogene. However, some splice variants of this gene may function as a tumor suppressor in neuroblastoma and other tumor types. Circular RNA variants were observed at this gene. [provided by RefSeq, Dec 2017]

Collection Method: clinical testing

The c.592C>T (p.L198F) alteration is located in exon 1 (coding exon 1) of the HDGFL1 gene. This alteration results from a C to T substitution at nucleotide position 592, causing the leucine (L) at amino acid position 198 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
