Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_178540.5(C1QTNF9):c.111T>A(p.Asn37Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000529 in 151,306 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 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. N37S) has been classified as Uncertain significance.

The c.111T>A (p.N37K) alteration is located in exon 2 (coding exon 1) of the C1QTNF9 gene. This alteration results from a T to A substitution at nucleotide position 111, causing the asparagine (N) at amino acid position 37 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
