6-39901459-G-T

Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2

The NM_001201427.2(DAAM2):​c.2969G>T​(p.Arg990Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00196 in 1,607,480 control chromosomes in the GnomAD database, including 7 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R990C) has been classified as Uncertain significance.

Genes affected
DAAM2 (HGNC:18143): (dishevelled associated activator of morphogenesis 2) Predicted to enable actin binding activity and small GTPase binding activity. Predicted to be involved in nervous system development and regulation of Wnt signaling pathway. Predicted to act upstream of or within determination of left/right symmetry. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]
MOCS1 (HGNC:7190): (molybdenum cofactor synthesis 1) Molybdenum cofactor biosynthesis is a conserved pathway leading to the biological activation of molybdenum. The protein encoded by this gene is involved in this pathway. This gene was originally thought to produce a bicistronic mRNA with the potential to produce two proteins (MOCS1A and MOCS1B) from adjacent open reading frames. However, only the first open reading frame (MOCS1A) has been found to encode a protein from the putative bicistronic mRNA, whereas additional splice variants are likely to produce a fusion between the two open reading frames. This gene is defective in patients with molybdenum cofactor deficiency, type A. A related pseudogene has been identified on chromosome 16. [provided by RefSeq, Nov 2017]
MOCS1 Gene-Disease associations (from GenCC):
  • sulfite oxidase deficiency due to molybdenum cofactor deficiency type A
