Variant chr8-86939603-A-G details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_173538.3(CNBD1):c.280A>G(p.Asn94Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00153 in 1,583,422 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. N94S) has been classified as Likely benign.

Ambry Genetics

Mar 28, 2023

The c.280A>G (p.N94D) alteration is located in exon 4 (coding exon 4) of the CNBD1 gene. This alteration results from a A to G substitution at nucleotide position 280, causing the asparagine (N) at amino acid position 94 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
