Genes affected

ENSG00000286110 (HGNC:):

PWRN1 (HGNC:33235): (Prader-Willi region non-protein coding RNA 1) This gene is located in the Prader-Willi syndrome (PWS) region of chromosome 15, which is known to undergo imprinting. The transcript is believed to be non-coding. It is bi-allelically expressed in testis and kidney, but mono-allelically expressed from the paternal allele in brain. This gene is poly-adenylated and is known to undergo alternative splicing. Transcript variants may represent part of a complex imprinting center-SNURF-SNRPN transcription unit. The contribution of this gene to the PWS phenotype is unknown, but it has been suggested that it may play a role in establishing paternal imprinting in the PWS region, perhaps by maintaining the paternal allele in an open chromatin configuration.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.789 is higher than 0.05.
