Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PM5

The NM_138967.4(SCAMP5):​c.538G>C​(p.Gly180Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G180W) has been classified as Likely pathogenic.

Genes affected

SCAMP5 (HGNC:30386): (secretory carrier membrane protein 5) Involved in positive regulation of cytokine production; regulation of vesicle-mediated transport; and response to endoplasmic reticulum stress. Located in Golgi apparatus; plasma membrane; and recycling endosome membrane. Is integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

SCAMP5 Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

  Inheritance: AD Classification: MODERATE, LIMITED Submitted by: Ambry Genetics, Illumina
• epilepsy

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr15-75018813-G-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 872248.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
