ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.03545004).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.000278 (407/1461814) while in subpopulation AMR AF= 0.000827 (37/44724). AF 95% confidence interval is 0.000617. There are 1 homozygotes in gnomad4_exome. There are 186 alleles in male gnomad4_exome subpopulation. Median coverage is 31.

The c.2273G>A (p.S758N) alteration is located in exon 16 (coding exon 15) of the DZIP1L gene. This alteration results from a G to A substitution at nucleotide position 2273, causing the serine (S) at amino acid position 758 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 758 of the DZIP1L protein (p.Ser758Asn). This variant is present in population databases (rs199601496, gnomAD 0.07%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with DZIP1L-related conditions. ClinVar contains an entry for this variant (Variation ID: 1503045). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
