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]

(HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a modified_residue Phosphoserine (size 0) in uniprot entity SGIP1_HUMAN
• PM2: Very rare variant in population databases, with high coverage

Sep 20, 2023

The c.505T>C (p.S169P) alteration is located in exon 10 (coding exon 10) of the SGIP1 gene. This alteration results from a T to C substitution at nucleotide position 505, causing the serine (S) at amino acid position 169 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
