Variant 1-2303939-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -17 ACMG points: 0P and 17B. BP4_StrongBP6_Very_StrongBP7BS2

The NM_003036.4(SKI):c.1311C>G(p.Ala437=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000143 in 1,611,702 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 Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. A437A) has been classified as Benign.

Genes affected

SKI (HGNC:10896): (SKI proto-oncogene) This gene encodes the nuclear protooncogene protein homolog of avian sarcoma viral (v-ski) oncogene. It functions as a repressor of TGF-beta signaling, and may play a role in neural tube development and muscle differentiation. [provided by RefSeq, Oct 2009]

Aug 11, 2015

p.Ala437Ala in exon 4 of SKI: This variant is not expected to have clinical sign ificance because it does not alter an amino acid residue and is not located with in the splice consensus sequence. It has been identified in 0.1% (13/10892) of L atino chromosomes and 0.02% (10/58550) of European chromosomes by the Exome Aggr egation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs140889128). -

Ambry Genetics

Dec 18, 2019

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
