Genetic Variant PIP5K1C:p.Asp663Asn (chr19-3633454-C-T) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_012398.3(PIP5K1C):c.1987G>A(p.Asp663Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000307 in 1,499,022 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D663G) has been classified as Uncertain significance.

Genes affected

PIP5K1C (HGNC:8996): (phosphatidylinositol-4-phosphate 5-kinase type 1 gamma) This locus encodes a type I phosphatidylinositol 4-phosphate 5-kinase. The encoded protein catalyzes phosphorylation of phosphatidylinositol 4-phosphate, producing phosphatidylinositol 4,5-bisphosphate. This enzyme is found at synapses and has been found to play roles in endocytosis and cell migration. Mutations at this locus have been associated with lethal congenital contractural syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Sep 2010]
