Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM2PM5PP3_StrongPP5_Moderate

The NM_001159773.2(CANT1):​c.899G>A​(p.Arg300His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000376 in 1,597,790 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 Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R300C) has been classified as Likely pathogenic.

Genes affected
CANT1 (HGNC:19721): (calcium activated nucleotidase 1) This protein encoded by this gene belongs to the apyrase family. It functions as a calcium-dependent nucleotidase with a preference for UDP. Mutations in this gene are associated with Desbuquois dysplasia with hand anomalies. Alternatively spliced transcript variants have been noted for this gene.[provided by RefSeq, Mar 2010]
