Variant chr12-56923942-T-C 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_148897.3(SDR9C7):c.833A>G(p.Asn278Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000394 in 152,164 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. N278K) has been classified as Uncertain significance.

The c.833A>G (p.N278S) alteration is located in exon 4 (coding exon 4) of the SDR9C7 gene. This alteration results from a A to G substitution at nucleotide position 833, causing the asparagine (N) at amino acid position 278 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
