Genes affected

BAIAP2L2 (HGNC:26203): (BAR/IMD domain containing adaptor protein 2 like 2) The protein encoded by this gene binds phosphoinositides and promotes the formation of planar or curved membrane structures. The encoded protein is found in RAB13-positive vesicles and at intercellular contacts with the plasma membrane. [provided by RefSeq, Dec 2012]

The c.1115C>G (p.S372C) alteration is located in exon 10 (coding exon 10) of the BAIAP2L2 gene. This alteration results from a C to G substitution at nucleotide position 1115, causing the serine (S) at amino acid position 372 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
