Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001080543.2(CACTIN):c.1832A>G(p.Lys611Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000028 in 1,606,786 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K611Q) has been classified as Uncertain significance.

The c.1832A>G (p.K611R) alteration is located in exon 10 (coding exon 10) of the CACTIN gene. This alteration results from a A to G substitution at nucleotide position 1832, causing the lysine (K) at amino acid position 611 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
