Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2
The NM_018249.6(CDK5RAP2):c.4665G>T(p.Gln1555His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000671 in 1,614,180 control chromosomes in the GnomAD database, including 7 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★).
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]
Computational evidence support a benign effect (MetaRNN=0.006692767).
BP6

BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00366 (558/152332) while in subpopulation AFR AF= 0.0127 (529/41578). AF 95% confidence interval is 0.0118. There are 2 homozygotes in gnomad4. There are 286 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
