Genetic Variant NM_000455.5:c.1071G>T (chr19-1223135-G-T) – ACMG Classification: Benign (-13 pts)

Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_000455.5(STK11):c.1071G>T(p.Glu357Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000054 in 1,611,940 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E357K) has been classified as Uncertain significance.

Genes affected

STK11 (HGNC:11389): (serine/threonine kinase 11) The protein encoded by this gene is a serine/threonine kinase that regulates cell polarity and energy metabolism and functions as a tumor suppressor. Mutations in this gene have been associated with the autosomal dominant Peutz-Jeghers syndrome, as well as with skin, pancreatic, and testicular cancers. [provided by RefSeq, May 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.040121347).

BP6

Variant 19-1223135-G-T is Benign according to our data. Variant chr19-1223135-G-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 412537.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000589 (86/1459604) while in subpopulation SAS AF = 0.000941 (81/86034). AF 95% confidence interval is 0.000776. There are 1 homozygotes in GnomAdExome4. There are 58 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 86 AD gene.
