Genes affected
GALT (HGNC:4135): (galactose-1-phosphate uridylyltransferase) Galactose-1-phosphate uridyl transferase (GALT) catalyzes the second step of the Leloir pathway of galactose metabolism, namely the conversion of UDP-glucose + galactose-1-phosphate to glucose-1-phosphate + UDP-galactose. The absence of this enzyme results in classic galactosemia in humans and can be fatal in the newborn period if lactose is not removed from the diet. The pathophysiology of galactosemia has not been clearly defined. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Classification made for transcript
Verdict is Uncertain_significance. Variant got 1 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 6 uncertain in NM_000155.4
PM2
?
Very rare variant in population databases, with high coverage;
BP4
?
Computational evidence support a benign effect (MetaRNN=0.17132968).
BP6
?
Variant 9-34647190-C-A is Benign according to our data. Variant chr9-34647190-C-A is described in ClinVar as [Benign]. Clinvar id is 3612.Status of the report is no_assertion_criteria_provided, 0 stars.
