Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM4PP5

The NM_006017.3(PROM1):c.1209_1229delGGATATACTCTCAGCATTCTC(p.Gln403_Ser410delinsHis) variant causes a disruptive inframe deletion change. The variant allele was found at a frequency of 0.00000501 in 1,597,318 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. Q403Q) has been classified as Likely benign.

Genes affected

PROM1 (HGNC:9454): (prominin 1) This gene encodes a pentaspan transmembrane glycoprotein. The protein localizes to membrane protrusions and is often expressed on adult stem cells, where it is thought to function in maintaining stem cell properties by suppressing differentiation. Mutations in this gene have been shown to result in retinitis pigmentosa and Stargardt disease. Expression of this gene is also associated with several types of cancer. This gene is expressed from at least five alternative promoters that are expressed in a tissue-dependent manner. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
