Genes affected

TCFL5 (HGNC:11646): (transcription factor like 5) Enables DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including negative regulation of transcription by RNA polymerase II; regulation of cell population proliferation; and spermatogenesis. Located in nucleus.

The c.1497C>G (p.I499M) alteration is located in exon 6 (coding exon 6) of the TCFL5 gene. This alteration results from a C to G substitution at nucleotide position 1497, causing the isoleucine (I) at amino acid position 499 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
