Genetic Variant CEP162:p.Arg1364His (chr6-84125191-C-T) – ACMG Classification: Benign (-8 pts)

Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_014895.4(CEP162):c.4091G>A(p.Arg1364His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000191 in 1,613,642 control chromosomes in the GnomAD database, including 6 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1364C) has been classified as Uncertain significance.

Genes affected

CEP162 (HGNC:21107): (centrosomal protein 162) Involved in cilium assembly. Located in axonemal microtubule; centriole; and centrosome. [provided by Alliance of Genome Resources, Apr 2022]

CEP162 links:

MRAP2 (HGNC:21232): (melanocortin 2 receptor accessory protein 2) This gene encodes a protein that modulates melanocortin receptor signaling. The encoded protein has been shown to interact with all known melanocortin receptors and may regulate both receptor trafficking and activation in response to ligands. Mice lacking a functional copy of this gene exhibit severe obesity and a mutation in this gene may be associated with severe obesity in human patients. [provided by RefSeq, Oct 2016]

The c.4091G>A (p.R1364H) alteration is located in exon 27 (coding exon 26) of the CEP162 gene. This alteration results from a G to A substitution at nucleotide position 4091, causing the arginine (R) at amino acid position 1364 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
