The c.307T>G (p.S103A) alteration is located in exon 2 (coding exon 2) of the WDR76 gene. This alteration results from a T to G substitution at nucleotide position 307, causing the serine (S) at amino acid position 103 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
