The c.337A>G (p.T113A) alteration is located in exon 1 (coding exon 1) of the KLHDC7A gene. This alteration results from a A to G substitution at nucleotide position 337, causing the threonine (T) at amino acid position 113 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
