Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_ModeratePP5_Moderate

The ENST00000447146.7(PQBP1):​c.731C>T​(p.Pro244Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000914 in 1,093,558 control chromosomes in the GnomAD database, with no homozygous occurrence. There are no hemizygote samples in GnomAD. 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. P244R) has been classified as Uncertain significance.

Genes affected
PQBP1 (HGNC:9330): (polyglutamine binding protein 1) This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked cognitive disability. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]
