Our verdict is Benign. Variant got -11 ACMG points: 2P and 13B. PM2BP4_StrongBP6_Very_StrongBP7
The NM_004287.5(GOSR2):c.6T>C(p.Asp2Asp) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000658 in 152,088 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 (★★).
GOSR2 (HGNC:4431): (golgi SNAP receptor complex member 2) This gene encodes a trafficking membrane protein which transports proteins among the medial- and trans-Golgi compartments. Due to its chromosomal location and trafficking function, this gene may be involved in familial essential hypertension. [provided by RefSeq, Mar 2016]
LRRC37A2 (HGNC:32404): (leucine rich repeat containing 37 member A2) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.6).
BP6
Variant 17-46923198-T-C is Benign according to our data. Variant chr17-46923198-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 700303.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.256 with no splicing effect.
Review Status: criteria provided, single submitter
Collection Method: clinical testing
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. -
