Variant rs773359554 details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PS1_ModeratePM1PM2PP5

The NM_014489.4(PGAP2):c.46C>T(p.Arg16Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000304 in 1,613,918 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R16Q) has been classified as Uncertain significance.

Genes affected

PGAP2 (HGNC:17893): (post-GPI attachment to proteins 2) The protein encoded by this gene plays a role in the maturation of glycosylphosphatidylinositol (GPI) anchors on GPI-anchored proteins. Mutations in this gene are associated with an autosomal recessive syndrome characterized by hyperphosphatasia and intellectual disability. [provided by RefSeq, Jul 2017]
