Genes affected

ATG7 (HGNC:16935): (autophagy related 7) This gene encodes an E1-like activating enzyme that is essential for autophagy and cytoplasmic to vacuole transport. The encoded protein is also thought to modulate p53-dependent cell cycle pathways during prolonged metabolic stress. It has been associated with multiple functions, including axon membrane trafficking, axonal homeostasis, mitophagy, adipose differentiation, and hematopoietic stem cell maintenance. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

The c.785C>G (p.S262C) alteration is located in exon 9 (coding exon 8) of the ATG7 gene. This alteration results from a C to G substitution at nucleotide position 785, causing the serine (S) at amino acid position 262 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
