Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_001039618.4(CREBZF):c.990T>A(p.His330Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,508 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. H330P) has been classified as Uncertain significance.

The c.990T>A (p.H330Q) alteration is located in exon 1 (coding exon 1) of the CREBZF gene. This alteration results from a T to A substitution at nucleotide position 990, causing the histidine (H) at amino acid position 330 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
