Genes affected

SHOC2 (HGNC:15454): (SHOC2 leucine rich repeat scaffold protein) This gene encodes a protein that consists almost entirely of leucine-rich repeats, a domain implicated in protein-protein interactions. The protein may function as a scaffold linking RAS to downstream signal transducers in the RAS/ERK MAP kinase signaling cascade. Mutations in this gene have been associated with Noonan-like syndrome with loose anagen hair. [provided by RefSeq, May 2010]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP6: Variant 10-111007515-T-G is Benign according to our data. Variant chr10-111007515-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 260160.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000466 (71/152330) while in subpopulation AFR AF= 0.00159 (66/41586). AF 95% confidence interval is 0.00128. There are 0 homozygotes in gnomad4. There are 42 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 71 AD gene.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Sep 09, 2019	Variant summary: SHOC2 c.1162-16T>G alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 9.5e-05 in 251340 control chromosomes, predominantly at a frequency of 0.0013 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 52 fold of the estimated maximal expected allele frequency for a pathogenic variant in SHOC2 causing Noonan Syndrome and Related Conditions phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. A ClinVar submitter (submission after 2014) cites the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. -
