Genes affected

TAF1L (HGNC:18056): (TATA-box binding protein associated factor 1 like) This locus is intronless, and apparently arose in the primate lineage from retrotransposition of the transcript from the multi-exon TAF1 locus on the X chromosome. The gene is expressed in male germ cells, and the product has been shown to function interchangeably with the TAF1 product. [provided by RefSeq, Aug 2015]

The c.5016C>G (p.N1672K) alteration is located in exon 1 (coding exon 1) of the TAF1L gene. This alteration results from a C to G substitution at nucleotide position 5016, causing the asparagine (N) at amino acid position 1672 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
