Genes affected
CDK5RAP2 (HGNC:18672): (CDK5 regulatory subunit associated protein 2) This gene encodes a regulator of CDK5 (cyclin-dependent kinase 5) activity. The protein encoded by this gene is localized to the centrosome and Golgi complex, interacts with CDK5R1 and pericentrin (PCNT), plays a role in centriole engagement and microtubule nucleation, and has been linked to primary microcephaly and Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 9-120458536-G-A is Benign according to our data. Variant chr9-120458536-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 158133.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-120458536-G-A is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=0.143 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000637 (97/152302) while in subpopulation SAS AF= 0.00145 (7/4826). AF 95% confidence interval is 0.000848. There are 1 homozygotes in gnomad4. There are 44 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 5 AR gene
