Genes affected

SGIP1 (HGNC:25412): (SH3GL interacting endocytic adaptor 1) SGIP1 functions as an endocytic protein that affects signaling by receptors in neuronal systems involved in energy homeostasis via its interaction with endophilins (see SH3GL3; MIM 603362) (Trevaskis et al., 2005 [PubMed 15919751] and Uezu et al., 2007 [PubMed 17626015]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3138195).

The c.4A>G (p.M2V) alteration is located in exon 1 (coding exon 1) of the SGIP1 gene. This alteration results from a A to G substitution at nucleotide position 4, causing the methionine (M) at amino acid position 2 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
