Position:

• chr15-38322323-AG-GA

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM1 PM2 BP6_Moderate

The NM_152594.3(SPRED1):​c.290_291delinsGA​(p.Lys97Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely benign (★). Another nucleotide change resulting in same amino acid change has been previously reported as Benignin ClinVar. Synonymous variant affecting the same amino acid position (i.e. K97K) has been classified as Benign.

Genes affected

SPRED1 (HGNC:20249): (sprouty related EVH1 domain containing 1) The protein encoded by this gene is a member of the Sprouty family of proteins and is phosphorylated by tyrosine kinase in response to several growth factors. The encoded protein can act as a homodimer or as a heterodimer with SPRED2 to regulate activation of the MAP kinase cascade. Defects in this gene are a cause of neurofibromatosis type 1-like syndrome (NFLS). [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM1: In a strand (size 8) in uniprot entity SPRE1_HUMAN there are 5 pathogenic changes around while only 2 benign (71%) in NM_152594.3
• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 15-38322323-AG-GA is Benign according to our data. Variant chr15-38322323-AG-GA is described in ClinVar as [Likely_benign]. Clinvar id is 536697.Status of the report is criteria_provided_single_submitter, 1 stars.
