Genes affected

RASSF4 (HGNC:20793): (Ras association domain family member 4) The function of this gene has not yet been determined but may involve a role in tumor suppression. Alternative splicing of this gene results in several transcript variants; however, most of the variants have not been fully described. [provided by RefSeq, Jul 2008]

RASSF4 links:

DEPP1 (HGNC:23355): (DEPP autophagy regulator 1) The expression of this gene is induced by fasting as well as by progesterone. The protein encoded by this gene contains a t-synaptosome-associated protein receptor (SNARE) coiled-coil homology domain and a peroxisomal targeting signal. Production of the encoded protein leads to phosphorylation and activation of the transcription factor ELK1. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.8).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00607 (923/152116) while in subpopulation AFR AF = 0.021 (873/41496). AF 95% confidence interval is 0.0199. There are 11 homozygotes in GnomAd4. There are 416 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 11 AR gene
