A single PIGM variant (NM_145167.2(PIGM):c.-270C>G)(rs587776528) has been associated with Glycosylphosphatidylinositol deficiency, (OMIM:610293) and as limited Gen2Phen gene for the same condition.
To date, this variant has only been reported in people of Arab or Turkish descent. Microsatellite- and SNP-based haplotypes encompassing PIGM reported in PMID:19168132, suggested that a founder effect in the two families (one Arab and one Turkish) was unlikely. However, subsequent occurrences of the variant in two additional unrelated Arab families (PMID: 31445883) might suggest that this variant is confined within the Middle Eastern populations.
Functional studies have shown that this variant reduces transcription of PIGM and blocks mannosylation of glycosylphosphatidylinositol anchor (PMID: 16767100).Created: 21 Nov 2023, 2:01 p.m. | Last Modified: 21 Nov 2023, 2:35 p.m.
