Genes affected

HYPK (HGNC:18418): (huntingtin interacting protein K) Enables protein N-terminus binding activity. Involved in negative regulation of apoptotic process and protein stabilization. Located in cytoplasm; microtubule cytoskeleton; and nucleoplasm. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

SERF2-C15ORF63 (HGNC:):

SERF2 (HGNC:10757): (small EDRK-rich factor 2) Involved in protein destabilization. Predicted to be located in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0017516911).
• BP6: Variant 15-43801560-G-A is Benign according to our data. Variant chr15-43801560-G-A is described in ClinVar as [Benign]. Clinvar id is 714534.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.605 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0126 (1915/152294) while in subpopulation AFR AF= 0.0437 (1818/41564). AF 95% confidence interval is 0.0421. There are 33 homozygotes in gnomad4. There are 912 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 33 AR gene
