Genes affected

DLEC1 (HGNC:2899): (DLEC1 cilia and flagella associated protein) The cytogenetic location of this gene is 3p21.3, and it is located in a region that is commonly deleted in a variety of malignancies. Down-regulation of this gene has been observed in several human cancers including lung, esophageal, renal tumors, and head and neck squamous cell carcinoma. In some cases, reduced expression of this gene in tumor cells is a result of aberrant promoter methylation. Several alternatively spliced transcripts have been observed that contain disrupted coding regions and likely encode nonfunctional proteins.[provided by RefSeq, Mar 2016]

ACAA1 (HGNC:82): (acetyl-CoA acyltransferase 1) This gene encodes an enzyme operative in the beta-oxidation system of the peroxisomes. Deficiency of this enzyme leads to pseudo-Zellweger syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

LOC105377033 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 3-38112369-T-C is Benign according to our data. Variant chr3-38112369-T-C is described in ClinVar as Benign. ClinVar VariationId is 785041.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00903 (1373/152082) while in subpopulation AFR AF = 0.0309 (1281/41442). AF 95% confidence interval is 0.0295. There are 21 homozygotes in GnomAd4. There are 627 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 21 AR gene
