Genes affected

TAF7L (HGNC:11548): (TATA-box binding protein associated factor 7 like) This gene is similar to a mouse gene that encodes a TATA box binding protein-associated factor, and shows testis-specific expression. The encoded protein could be a spermatogenesis-specific component of the DNA-binding general transcription factor complex TFIID. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

The c.866A>G (p.K289R) alteration is located in exon 9 (coding exon 9) of the TAF7L gene. This alteration results from a A to G substitution at nucleotide position 866, causing the lysine (K) at amino acid position 289 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
