ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.23861992).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000113 (165/1454294) while in subpopulation SAS AF= 0.00146 (124/85182). AF 95% confidence interval is 0.00125. There are 2 homozygotes in gnomad4_exome. There are 114 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

Ambry Genetics

May 06, 2024

The c.1621G>A (p.G541R) alteration is located in exon 11 (coding exon 11) of the LMF1 gene. This alteration results from a G to A substitution at nucleotide position 1621, causing the glycine (G) at amino acid position 541 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
