Genes affected
MAGEL2 (HGNC:6814): (MAGE family member L2) Prader-Willi syndrome (PWS) is caused by the loss of expression of imprinted genes in chromosome 15q11-q13 region. Affected individuals exhibit neonatal hypotonia, developmental delay, and childhood-onset obesity. Necdin (NDN), a gene involved in the terminal differentiation of neurons, localizes to this region of the genome and has been implicated as one of the genes responsible for the etiology of PWS. This gene is structurally similar to NDN, is also localized to the PWS chromosomal region, and is paternally imprinted, suggesting a possible role for it in PWS. [provided by RefSeq, Oct 2010]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.87).
BP6
Variant 15-23644514-A-G is Benign according to our data. Variant chr15-23644514-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 158813.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.872 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00878 (1336/152132) while in subpopulation AFR AF= 0.0296 (1227/41486). AF 95% confidence interval is 0.0282. There are 19 homozygotes in gnomad4. There are 609 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 1336 AD gene.
