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.4975G>C (p.G1659R) alteration is located in exon 1 (coding exon 1) of the TAF1L gene. This alteration results from a G to C substitution at nucleotide position 4975, causing the glycine (G) at amino acid position 1659 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
