Variant 1-1336180-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP3BS2

The NM_001330311.2(DVL1):c.2050A>G(p.Met684Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000953 in 1,573,282 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. M684T) has been classified as Likely benign.

Genes affected

DVL1 (HGNC:3084): (dishevelled segment polarity protein 1) DVL1, the human homolog of the Drosophila dishevelled gene (dsh) encodes a cytoplasmic phosphoprotein that regulates cell proliferation, acting as a transducer molecule for developmental processes, including segmentation and neuroblast specification. DVL1 is a candidate gene for neuroblastomatous transformation. The Schwartz-Jampel syndrome and Charcot-Marie-Tooth disease type 2A have been mapped to the same region as DVL1. The phenotypes of these diseases may be consistent with defects which might be expected from aberrant expression of a DVL gene during development. [provided by RefSeq, Jul 2008]

The c.1975A>G (p.M659V) alteration is located in exon 15 (coding exon 15) of the DVL1 gene. This alteration results from a A to G substitution at nucleotide position 1975, causing the methionine (M) at amino acid position 659 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
