Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_001014286.3(SUPT20H):c.865T>C(p.Cys289Arg) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000153 in 1,566,520 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★).

The c.865T>C (p.C289R) alteration is located in exon 12 (coding exon 11) of the SUPT20H gene. This alteration results from a T to C substitution at nucleotide position 865, causing the cysteine (C) 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. -
