Variant chr11-111357617-G-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_006235.3(POU2AF1):c.284C>A(p.Thr95Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,461,726 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. T95P) has been classified as Uncertain significance.

Feb 07, 2023

The c.284C>A (p.T95N) alteration is located in exon 4 (coding exon 4) of the POU2AF1 gene. This alteration results from a C to A substitution at nucleotide position 284, causing the threonine (T) at amino acid position 95 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
