Genes affected

TBPL1 (HGNC:11589): (TATA-box binding protein like 1) This gene encodes a member of the TATA box-binding protein family. TATA box-binding proteins play a critical role in transcription by RNA polymerase II as components of the transcription factor IID (TFIID) complex. The encoded protein does not bind to the TATA box and initiates transcription from TATA-less promoters. This gene plays a critical role in spermatogenesis, and single nucleotide polymorphisms in this gene may be associated with male infertility. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 3. [provided by RefSeq, Nov 2011]

The c.366G>C (p.K122N) alteration is located in exon 5 (coding exon 4) of the TBPL1 gene. This alteration results from a G to C substitution at nucleotide position 366, causing the lysine (K) at amino acid position 122 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
