Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2

The NM_024007.5(EBF1):c.1265C>A(p.Pro422Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000419 in 1,598,904 control chromosomes in the GnomAD database, including 1 homozygotes. 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. P422L) has been classified as Uncertain significance.

The c.1265C>A (p.P422Q) alteration is located in exon 13 (coding exon 13) of the EBF1 gene. This alteration results from a C to A substitution at nucleotide position 1265, causing the proline (P) at amino acid position 422 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
