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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0063773096).

BP6

Variant 15-23644726-G-C is Benign according to our data. Variant chr15-23644726-G-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 193399.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00338 (514/152244) while in subpopulation NFE AF = 0.0059 (401/68014). AF 95% confidence interval is 0.00542. There are 2 homozygotes in GnomAd4. There are 240 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 514 AD gene.
