Genes affected

STARD3NL (HGNC:19169): (STARD3 N-terminal like) This gene encodes a late-endosomal protein that contains a conserved MENTAL (MLN64 N-terminal) domain. The encoded protein binds cholesterol molecules and may play a role in endosomal cholesterol transport through interactions with metastatic lymph node protein 64 (MLN64).

The c.241G>C (p.E81Q) alteration is located in exon 3 (coding exon 2) of the STARD3NL gene. This alteration results from a G to C substitution at nucleotide position 241, causing the glutamic acid (E) at amino acid position 81 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
