Submissions by phenotype
not specified Uncertain:1
The c.494C>G (p.S165C) alteration is located in exon 3 (coding exon 3) of the TAF4B gene. This alteration results from a C to G substitution at nucleotide position 494, causing the serine (S) at amino acid position 165 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
