Genes affected

EVC (HGNC:3497): (EvC ciliary complex subunit 1) This gene encodes a protein containing a leucine zipper and a transmembrane domain. This gene has been implicated in both Ellis-van Creveld syndrome (EvC) and Weyers acrodental dysostosis. [provided by RefSeq, Jul 2008]

CRMP1 (HGNC:2365): (collapsin response mediator protein 1) This gene encodes a member of a family of cytosolic phosphoproteins expressed exclusively in the nervous system. The encoded protein is thought to be a part of the semaphorin signal transduction pathway implicated in semaphorin-induced growth cone collapse during neural development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP6: Variant 4-5748087-C-CCTTTG is Benign according to our data. Variant chr4-5748087-C-CCTTTG is described in ClinVar as Likely_benign. ClinVar VariationId is 1186208.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0115 (1750/152096) while in subpopulation AFR AF = 0.0393 (1631/41468). AF 95% confidence interval is 0.0377. There are 36 homozygotes in GnomAd4. There are 821 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 36 AD,Unknown,AR gene
