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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.15634).

Ambry Genetics

Jul 12, 2023

The c.733A>G (p.T245A) alteration is located in exon 13 (coding exon 13) of the SGIP1 gene. This alteration results from a A to G substitution at nucleotide position 733, causing the threonine (T) at amino acid position 245 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
