The c.437C>G (p.A146G) alteration is located in exon 4 (coding exon 4) of the SPDYE4 gene. This alteration results from a C to G substitution at nucleotide position 437, causing the alanine (A) at amino acid position 146 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
