Genes affected

NEGR1 (HGNC:17302): (neuronal growth regulator 1) Predicted to act upstream of or within several processes, including feeding behavior; locomotory behavior; and positive regulation of neuron projection development. Predicted to be located in extracellular region and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

NEGR1-IT1 (HGNC:41432): (NEGR1 intronic transcript 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0184 (2802/151958) while in subpopulation NFE AF= 0.0277 (1882/67938). AF 95% confidence interval is 0.0267. There are 35 homozygotes in gnomad4. There are 1379 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 35 gene
