Genes affected

MIA3 (HGNC:24008): (MIA SH3 domain ER export factor 3) Enables cargo receptor activity. Involved in several processes, including COPII-coated vesicle cargo loading; cell migration involved in sprouting angiogenesis; and regulation of leukocyte migration. Located in endoplasmic reticulum exit site and endoplasmic reticulum membrane. Is integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004011303).
• BP6: Variant 1-222628319-A-T is Benign according to our data. Variant chr1-222628319-A-T is described in ClinVar as [Benign]. Clinvar id is 782938.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0125 (18287/1461378) while in subpopulation NFE AF= 0.0152 (16942/1111876). AF 95% confidence interval is 0.015. There are 169 homozygotes in gnomad4_exome. There are 8814 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 3 AR gene
